  FR [Bibliography] <http://eel.is/c++draft/bibliography> Unify
  references to Unicode

GitHub nbballot issue #412
<https://github.com/cplusplus/nbballot/issues/412>.


    Comment:

The C++ standard references no less than 4 different Unicode versions
(12, 13, 14, 15).


    Proposed change:

Please refer to Unicode 15 and associated UAX documents consistently in
the Bibliography section and impacted sections


    SG16 chair notes:

This comment is related to FR 5.3p5.2 [lex.charset] Codepoint names in
identifiers <https://github.com/cplusplus/nbballot/issues/423>.

Some of the Unicode versions referenced in the comment come from the
Unicode version that corresponds to an ISO/IEC 10646 reference.

As Corentin described in a message to the SG16 mailing list
<https://lists.isocpp.org/sg16/2022/10/3474.php>, there are
ramifications to referring to ISO/IEC 10646 to satisfy some Unicode
needs and to the Unicode Standard for others. The different release
cadence for ISO/IEC 10646 implies that we either have to 1) live with
references to multiple Unicode versions, 2) restrict references to
Unicode versions associated with the current ISO/IEC 10646 standard, or
3) discontinue referencing ISO/IEC 10646 (and make the case to the ISO
that the limited scope of ISO/IEC 10646 makes it not suitable for our
purposes).


    Candidate polls:

  * [FR-XX]: SG16 recommends accepting the comment in the direction of
    the proposed change by 1) replacing references to ISO/IEC 10646 with
    references to the Unicode Standard, and 2) updating all Unicode
    references to Unicode 15.
  * [FR-XX]: SG16 recommends resolving the comment by restricting
    references to the Unicode Standard to the version that corresponds
    to the referenced version of ISO/IEC 10646.
  * [FR-XX]: SG16 recommends rejecting the comment as not a defect.

Tom.
