This document specifies a set of Label Generation Rules (LGR) for Bosnian in Cyrillic script using a language-specific repertoire for the second level domain or domains identified above. The format of this file follows [RFC 7940]. This LGR is adapted from the “Reference LGR for the Second Level for the Bosnian (Cyrillic) Language” [Ref-LGR-bs-Cyrl], for details, see Change History below.
Standalone LGR: This LGR is designed to be used in a zone that does not cater to IDNs other than those valid under this LGR. This LGR lacks features that would allow its use in the context of another LGR in the same zone, and it may contain other features incompatible with such use.
All references converge on 30 Cyrillic code points (23 + 7 as defined by RFC 5992 [130]), identical to the Serbian Cyrillic set.
There is no IDN table published in the IANA Repository of IDN Practices by .ba (Bosnia-Herzegovina cctld). Because the repertoire is identical to Serbian Cyrillic, any IDNA practice for Bosnian is likely to follow the same guidelines as for Serbian.
There is some historic use of U+044C CYRILLIC SMALL LETTER SOFT SIGN, U+044E CYRILLIC SMALL LETTER YU, and U+0461 CYRILLIC SMALL LETTER OMEGA, attested in [201] but included in a repertoire with terms that call for their exclusion in modern use: “Some of the letters used in the Modern Bosnian Cyrillic alphabet were not used in this version, and there are some extra letters that are no longer used." The 3 letters mentioned above belong to these ‘extra’ letters.
Letters documented in some references but not included:
U+044C CYRILLIC SMALL LETTER SOFT SIGN
U+044E CYRILLIC SMALL LETTER YU
U+0461 CYRILLIC SMALL LETTER OMEGA
None.
Any code points outside the Bosnian (Cyrillic) Language repertoire that are targets for out-of-repertoire variants would be included here only if the variant is listed in this file. In this case they are identified as a reflexive (identity) variant of type “out-of-repertoire-var”. Whether or not they are listed, they do not form part of the repertoire.
There are no variants defined between Cyrillic letters.
No ASCII Variants: Note that this LGR does not contain definitions for “blocked” variants for letters that look indistinguishable from ASCII letters (homoglyphs). If concurrent use of LDH labels is desired, the resulting conflicts can be handled by using the “Common LGR” in processing. For details, see Section 3, “Use of Multiple Reference LGRs in the Same Zone” in [Level-2-Overview].
This LGR does not define named character classes.
By default, the LGR includes the rules and actions to implement the following restrictions mandated by the IDNA protocol. They are marked with ⍟.
This LGR includes the default actions for LGRs as well as the action needed to invalidate labels with misplaced combining marks. They are marked with ⍟. For a description see [RFC 7940].
Variant-related actions included to facilitate integration as appropriate.
The LGR in this document has been adapted from the corresponding Reference LGR for the Second Level. The Second Level Reference LGR for the Bosnian (Cyrillic) Language was developed by Michel Suignard and Asmus Freytag, including input by Michael Everson, Nicholas Ostler, and Wil Tan, and based on multiple open public consultations.
Language tag has been updated.
Unicode Version has been updated.
This version modifies the Second Level Reference LGR for the Bosnian (Cyrillic) Language [Ref-LGR-bs-Cyrl] by injecting the complete (maximal) set of cross-repertoire variants, including any imposed by transitivity. Injected variants are marked by special comments. Any character classes, context and WLE rules required for testing are also imported. In all other respects, description or annotations have not been updated to reflect the injected variants. Any LGR elements that might pose a possible conflict when the LGR is used with the Common LGR for cross-repertoire variant resolution are clearly marked. All modifications are carried out mechanically; there may be an occasional context rule or similar that is injected because its definition relates to some repertoire element even though it can never be triggered by any label valid under the modified LGR.

In the listing of the repertoire by code point, references starting from [0] refer to the version of the Unicode Standard in which the corresponding code point was initially encoded. Other references (starting from [100]) document usage of code points. Entries in the table may have multiple source reference values. In the listing of whole label evaluation and context rules, reference [150] indicates the source for common rules. For more details, see the Table of References below.
