RFC 5892 IDNA Code Points August 2010
1. Introduction
RFC 4690 [RFC4690] suggests an inclusion-based approach for selecting
the code points from The Unicode Standard [Unicode52] that should be
included in the list of code points that may be used in
Internationalized Domain Names.
Specifically, RFC 4690 [RFC4690] says the following:
The IAB has concluded that there is a consensus within the broader
community that lists of code points should be specified by the use
of an inclusion-based mechanism (i.e., identifying the characters
that are permitted), rather than by excluding a small number of
characters from the total Unicode set as Stringprep [RFC3454] and
Nameprep [RFC3491] do today. That conclusion should be reviewed
by the IETF community and action taken as appropriate.
This document reviews and classifies the collections of code points
in the Unicode character set by examining various properties of the
code points. It then defines an algorithm for determining a derived
property value. It specifies a procedure, and not a table, of code
points so that the algorithm can be used to determine code point sets
independent of the version of Unicode that is in use.
This document is not intended to specify precisely how these property
values are to be applied in IDN labels. That information appears in
the Protocol document [RFC5891], but it is important to understand
that the assignment of a value of this property to a particular
character is not sufficient to determine whether it can be used in a
given label. In particular, some combinations of allowed code points
are not advisable for use in IDNs due to rules specific to a script
or class of characters. The requirement for such rules is linked to
the operations in the Protocol document and especially to the
characters designated as requiring contextual rules.
The value of the property is to be interpreted as follows.
o PROTOCOL VALID: Those that are allowed to be used in IDNs. Code
points with this property value are permitted for general use in
IDNs. However, that a label consists only of code points that
have this property value does not imply that the label can be used
in DNS. See the Protocol document for algorithms to make
decisions about labels in domain names. The abbreviated term
PVALID is used to refer to this value in the rest of this
document.
Faltstrom Standards Track [Page 3]
RFC 5892 IDNA Code Points August 2010
o CONTEXTUAL RULE REQUIRED: Some characteristics of the character,
such as it being invisible in certain contexts or problematic in
others, require that it not be used in labels unless specific
other characters or properties are present. The abbreviated term
CONTEXT is used to refer to this value in the rest of this
document. There are two subdivisions of CONTEXTUAL RULE REQUIRED,
one for Join_controls (called CONTEXTJ) and for other characters
(called CONTEXTO). These are discussed in more detail below and
in the Protocol document.
o DISALLOWED: Those that should clearly not be included in IDNs.
Code points with this property value are not permitted in IDNs.
o UNASSIGNED: Those code points that are not designated (i.e., are
unassigned) in the Unicode Standard.
The mechanisms described here allow determination of the value of the
property for future versions of Unicode (including characters added
after Unicode 5.2). Changes in Unicode properties that do not affect
the outcome of this process do not affect IDN. For example, a
character can have its Unicode General_Category value (see
[Unicode52]) change from So to Sm or from Lo to Ll, without affecting
the algorithm results. Moreover, even if such changes were the
result, the BackwardCompatible list (Section 2.7) can be adjusted to
ensure the stability of the results.
Some code points need to be allowed in exceptional circumstances but
should be excluded in all other cases; these rules are also described
in other documents. The most notable of these are the Join Control
characters, U+200D ZERO WIDTH JOINER and U+200C ZERO WIDTH
NON-JOINER. Both of them have the derived property value CONTEXTJ.
A character with the derived property value CONTEXTJ or CONTEXTO
(CONTEXTUAL RULE REQUIRED) is not to be used unless an appropriate
rule has been established and the context of the character is
consistent with that rule. It is invalid to either register a string
containing these characters or even to look one up unless such a
contextual rule is found and satisfied. Please see Appendix A, "The
Contextual Rules Registry", for more information.
This document is part of a series that, together, constitute a
proposal for updating the IDNA standards to resolve issues uncovered
in recent years, cover a broader range of scripts, and provide for
migration to newer versions of Unicode. See the Rationale document
[RFC5894] for a broader discussion.
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
"SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
document are to be interpreted as described in RFC 2119 [RFC2119].

RFC 5892 IDNA Code Points August 2010
2. Category Definitions Used to Calculate Derived Property Value
The derived property obtains its value based on a two-step procedure.
First, characters are placed in one or more character categories
based on either core properties defined by the Unicode Standard or by
treating the code point as an exception and addressing the code point
by its code point value. These categories are not mutually
exclusive.
In the second step, set operations are used with these categories to
determine the values for an IDN-specific property. Those operations
are specified in Section 3.
Unicode property names and property value names may have short
abbreviations, such as gc for the General_Category property, and Ll
for the Lowercase_Letter property value of the gc property.
In the following specification of categories, the operation that
returns the value of a particular Unicode character property for a
code point is designated by using the formal name of that property
(from PropertyAliases.txt) followed by '(cp)'. For example, the
value of the General_Category property for a code point is indicated
by General_Category(cp).
2.1. LetterDigits (A)
A: General_Category(cp) is in {Ll, Lu, Lo, Nd, Lm, Mn, Mc}
These rules identify characters commonly used in mnemonics and often
informally described as "language characters". In general, only code
points assigned to this category are suitable for use in IDN.
For more information, see Section 4.5 of The Unicode Standard
[Unicode].
The categories used in this rule are:
o Ll - Lowercase_Letter
o Lu - Uppercase_Letter
o Lo - Other_Letter
o Nd - Decimal_Number
o Lm - Modifier_Letter
Faltstrom Standards Track [Page 5]
RFC 5892 IDNA Code Points August 2010
o Mn - Nonspacing_Mark
o Mc - Spacing_Mark
2.2. Unstable (B)
B: toNFKC(toCaseFold(toNFKC(cp))) != cp
This category is used to group the characters that are not stable
under Normalization Form K (NFKC) and case folding. In general,
these code points are not suitable for use for IDN.
The toCaseFold() operation is defined in Section 3.13 of The Unicode
Standard [Unicode].
The toNFKC() operation returns the code point in normalization form
KC. For more information, see Section 5 of Unicode Standard Annex
#15 [TR15].
It should be noted that NFKC is used, although Normalization Form C
(NFC) is used in the "IDNA Protocol" document [RFC5891].
2.3. IgnorableProperties (C)
C: Default_Ignorable_Code_Point(cp) = True or
White_Space(cp) = True or
Noncharacter_Code_Point(cp) = True
This category is used to group code points that are not recommended
for use in identifiers. In general, these code points are not
suitable for use in an IDN.
The definition for Default_Ignorable_Code_Point can be found in
DerivedCoreProperties.txt [DerivedCoreProperties] and is at the time
of Unicode 5.2:
Other_Default_Ignorable_Code_Point + Cf (Format characters)
+ Variation_Selector - White_Space - FFF9..FFFB (Annotation
Characters) - 0600..0603, 06DD, 070F (exceptional Cf characters
that should be visible)
Faltstrom Standards Track [Page 6]
RFC 5892 IDNA Code Points August 2010
2.4. IgnorableBlocks (D)
D: Block(cp) is in {Combining Diacritical Marks for Symbols,
Musical Symbols, Ancient Greek Musical Notation}
This category is used to identify code points that are not useful in
mnemonics or that are otherwise impractical for IDN use. In general,
these code points are not suitable for use for IDN.
The definition of blocks can be found in Blocks.txt [BlockNames].
2.5. LDH (E)
E: cp is in {002D, 0030..0039, 0061..007A}
This category is used in the second step to preserve the traditional
"hostname" (LDH -- as described in the Definitions document
[RFC5890]) characters ('-', 0-9, and a-z). In general, these code
points are suitable for use for IDN. Note that there are other rules
regarding the code point U+002D HYPHEN-MINUS that are specified in
the IDNA Protocol Specification [RFC5891].
2.6. Exceptions (F)
F: cp is in {00B7, 00DF, 0375, 03C2, 05F3, 05F4, 0640, 0660,
0661, 0662, 0663, 0664, 0665, 0666, 0667, 0668,
0669, 06F0, 06F1, 06F2, 06F3, 06F4, 06F5, 06F6,
06F7, 06F8, 06F9, 06FD, 06FE, 07FA, 0F0B, 3007,
302E, 302F, 3031, 3032, 3033, 3034, 3035, 303B,
30FB}
This category explicitly lists code points for which the category
cannot be assigned using only the core property values that exist in
the Unicode standard. The values are according to the table below:
PVALID -- Would otherwise have been DISALLOWED
00DF; PVALID # LATIN SMALL LETTER SHARP S
03C2; PVALID # GREEK SMALL LETTER FINAL SIGMA
06FD; PVALID # ARABIC SIGN SINDHI AMPERSAND
06FE; PVALID # ARABIC SIGN SINDHI POSTPOSITION MEN

Faltstrom Standards Track [Page 8]
RFC 5892 IDNA Code Points August 2010
2.7. BackwardCompatible (G)
G: cp is in {}
This category includes the code points that property values in
versions of Unicode after 5.2 have changed in such a way that the
derived property value would no longer be PVALID or DISALLOWED. If
changes are made to future versions of Unicode so that code points
might change the property value from PVALID or DISALLOWED, then this
table can be updated and keep special exception values so that the
property values for code points stay stable.
2.8. JoinControl (H)
H: Join_Control(cp) = True
This category consists of Join Control characters (i.e., they are not
in LetterDigits (Section 2.1) but are still required in IDN labels
under some circumstances).
2.9. OldHangulJamo (I)
I: Hangul_Syllable_Type(cp) is in {L, V, T}
This category consists of all conjoining Hangul Jamo (Leading Jamo,
Vowel Jamo, and Trailing Jamo).
Elimination of conjoining Hangul Jamo from the set of PVALID
characters results in restricting the set of Korean PVALID characters
just to preformed, modern Hangul syllable characters. Old Hangul
syllables, which must be spelled with sequences of conjoining Hangul
Jamo, are not PVALID for IDNs.
2.10. Unassigned (J)
J: General_Category(cp) is in {Cn} and
Noncharacter_Code_Point(cp) = False
This category consists of code points in the Unicode character set
that are not (yet) assigned. It should be noted that Unicode
distinguishes between "unassigned code points" and "unassigned
characters". The unassigned code points are all but (Cn -
Noncharacters), while the unassigned *characters* are all but (Cn +
Cs).
Faltstrom Standards Track [Page 9]
RFC 5892 IDNA Code Points August 2010
3. Calculation of the Derived Property
As described above (Section 1) and in more detail in the IDNA
Protocol document [RFC5891], possible values of the IDN property are:
o PVALID
o CONTEXTJ
o CONTEXTO
o DISALLOWED
o UNASSIGNED
The algorithm to calculate the value of the derived property is as
follows. If the name of a rule (such as Exception) is used, that
implies the set of code points that the rule defines, while the same
name as a function call (such as Exception(cp)) implies the value cp
has in the Exceptions table.
If .cp. .in. Exceptions Then Exceptions(cp);
Else If .cp. .in. BackwardCompatible Then BackwardCompatible(cp);
Else If .cp. .in. Unassigned Then UNASSIGNED;
Else If .cp. .in. LDH Then PVALID;
Else If .cp. .in. JoinControl Then CONTEXTJ;
Else If .cp. .in. Unstable Then DISALLOWED;
Else If .cp. .in. IgnorableProperties Then DISALLOWED;
Else If .cp. .in. IgnorableBlocks Then DISALLOWED;
Else If .cp. .in. OldHangulJamo Then DISALLOWED;
Else If .cp. .in. LetterDigits Then PVALID;
Else DISALLOWED;
4. Code Points
The categories and rules defined in Sections 2 and 3 apply to all
Unicode code points. The table in Appendix B shows, for illustrative
purposes, the consequences of the categories and classification
rules, and the resulting property values.
The list of code points that can be found in Appendix B is
non-normative. Sections 2 and 3 are normative.
Faltstrom Standards Track [Page 10]
RFC 5892 IDNA Code Points August 2010
5. IANA Considerations
5.1. IDNA-Derived Property Value Registry
IANA has created a registry with the derived properties for the
versions of Unicode released after (and including) version 5.2. The
derived property value is to be calculated in cooperation with a
designated expert [RFC5226] according to the specifications in
Sections 2 and 3 and not by copying the non-normative table found in
Appendix B.
If non-backward-compatible changes or other problems arise during the
creation or designated expert review of the table of derived property
values, they should be flagged for the IESG. Changes to the rules
(as specified in Sections 2 and 3), including BackwardCompatible
(Section 2.7) (a set that is at release of this document is empty)
require IETF Review, as described in RFC 5226 [RFC5226].
5.2. IDNA Context Registry
For characters that are defined in the IDNA derived property value
registry (Section 5.1) as CONTEXTO or CONTEXTJ and that therefore
require a contextual rule, IANA has created and now maintains a list
of approved contextual rules. Additions or changes to these rules
require IETF Review, as described in [RFC5226].
Appendix A contains further discussion and a table from which that
registry can be initialized.
5.2.1. Template for Context Registry
The following information is to be given when a new rule is created.
Name: Unique name of the rule
Code point: Rule that should be applied when this code point
exists in the label
Overview: Description in plain English on what the rule verifies
Lookup: Should the rule be applied at time of lookup?
Rule Set: The set of rules, with a reference to the defining
document.

RFC 5892 IDNA Code Points August 2010
6. Security Considerations
Security Considerations for this version of IDNA, except for the
special issues associated with right-to-left scripts and characters,
are described in the Definitions document [RFC5890]. Specific issues
for labels containing characters associated with scripts written
right to left appear in the Bidi document [RFC5893].

RFC 5892 IDNA Code Points August 2010
Appendix A. Contextual Rules Registry
As discussed in Section 5.2 and in the IANA Considerations section of
the Rationale document [RFC5894], a registry of rules that define the
contexts in which particular PROTOCOL-VALID characters, characters
associated with a requirement for Contextual Information, are
permitted. These rules are expressed as tests on the label in which
the characters appear (all, or any part of, the label may be tested).
The grammatical rules are expressed in pseudo-code. The conventions
used for that pseudo-code are explained here.
Each rule is constructed as a Boolean expression that evaluates to
either True or False. A simple "True;" or "False;" rule sets the
default result value for the rule set. Subsequent conditional rules
that evaluate to True or False may re-set the result value.
A special value "Undefined" is used to deal with any error
conditions, such as an attempt to test a character before the start
of a label or after the end of a label. If any term of a rule
evaluates to Undefined, further evaluation of the rule immediately
terminates, as the result value of the rule will itself be Undefined.
cp represents the code point to be tested.
FirstChar is a special term that denotes the first code point in a
label.
LastChar is a special term that denotes the last code point in a
label.
.eq. represents the equality relation.
A .eq. B evaluates to True if A equals B.
.is. represents checking the position in a label.
A .is. B evaluates to True if A and B have same position in
the same label.
.ne. represents the non-equality relation.
A .ne. B evaluates to True if A is not equal to B.
.in. represents the set inclusion relation.
A .in. B evaluates to True if A is a member of the set B.
Faltstrom Standards Track [Page 13]
RFC 5892 IDNA Code Points August 2010
A functional notation, Function_Name(cp), is used to express either
string positions within a label, Boolean character property tests of
a code point, or a regular expression match. When such function
names refer to Boolean character property tests, the function names
use the exact Unicode character property name for the property in
question, and "cp" is evaluated as the Unicode value of the code
point to be tested, rather than as its position in the label. When
such function names refer to string positions within a label, "cp" is
evaluated as its position in the label.
RegExpMatch(X) takes as its parameter X a schematic regular
expression consisting of a mix of Unicode character property values
and literal Unicode code points.
Script(cp) returns the value of the Unicode Script property, as
defined in Scripts.txt in the Unicode Character Database.
Canonical_Combining_Class(cp) returns the value of the Unicode
Canonical_Combining_Class property, as defined in UnicodeData.txt in
the Unicode Character Database.
Before(cp) returns the code point of the character immediately
preceding cp in logical order in the string representing the label.
Before(FirstChar) evaluates to Undefined.
After(cp) returns the code point of the character immediately
following cp in logical order in the string representing the label.
After(LastChar) evaluates to Undefined.
Note that "Before" and "After" do not refer to the visual display
order of the character in a label, which may be reversed or otherwise
modified by the bidirectional algorithm for labels including
characters from scripts written right to left. Instead, "Before" and
"After" refer to the network order of the character in the label.
The clauses "Then True" and "Then False" imply exit from the
pseudo-code routine with the corresponding result.
Repeated evaluation for all characters in a label makes use of the
special construct:
For All Characters:
Expression;
End For;
Faltstrom Standards Track [Page 14]
RFC 5892 IDNA Code Points August 2010
This construct requires repeated evaluation of "Expression" for each
code point in the label, starting from FirstChar and proceeding to
LastChar.
The different fields in the rules are to be interpreted as follows:
Code point:
The code point, or code points, to which this rule is to be
applied. Normally, this implies that if any of the code points in
a label is as defined, then the rules should be applied. If
evaluated to True, the code point is OK as used; if evaluated to
False, it is not OK.
Overview:
A description of the goal with the rule, in plain English.
Lookup:
True if application of this rule is recommended at lookup time;
False otherwise.
Rule Set:
The rule set itself, as described above.
Appendix A.1. ZERO WIDTH NON-JOINER
Code point:
U+200C
Overview:
This may occur in a formally cursive script (such as Arabic) in a
context where it breaks a cursive connection as required for
orthographic rules, as in the Persian language, for example. It
also may occur in Indic scripts in a consonant-conjunct context
(immediately following a virama), to control required display of
such conjuncts.
Lookup:
True

Appendix B. Code Points 0x0000 - 0x10FFFF
If one applies the rules (Section 3) to the code points 0x0000 to
0x10FFFF to Unicode 5.2, the result is as follows.
This list is non-normative, and only included for illustrative
purposes. Specifically, what is displayed in the third column is not
the formal name of the code point (as defined in Section 4.8 of The
Unicode Standard [Unicode52]). The differences exist, for example,
for the code points that have the code point value as part of the
name (for example, CJK UNIFIED IDEOGRAPH-4E00) and the naming of
Hangul syllables. For many code points, what you see is the official
name.
