             Bug #: 14094
           Summary: Update locale data to Unicode 6.1
           Product: glibc
           Version: 2.15
            Status: NEW
          Severity: normal
          Priority: P2
         Component: localedata
        AssignedTo: unassigned@sourceware.org
        ReportedBy: jsm28@gcc.gnu.org
                CC: libc-locales@sources.redhat.com
    Classification: Unclassified


The Unicode locale data - character map and LC_CTYPE information - should be
updated from Unicode 6.1 (the character map is currently based on 6.0, and
LC_CTYPE is currently based on 5.0).  This should be done with proper
automation and wiki documentation being added of how to do future updates.  I
identified the following tasks at
<http://sourceware.org/ml/libc-alpha/2012-05/msg00590.html>:

* Ensure the character type data in localedata/charmaps/i18n can be
  properly reproduced from Unicode 5.0 data using gen-unicode-ctype.c,
  adapting gen-unicode-ctype.c as needed to replicate any changes that
  may have been made not using that program.

* Update the character type data to Unicode 6.1, removing any local
  hacks from gen-unicode-ctype.c that are no longer needed.
  (10646:2012, corresponding to Unicode 6.1, appears to be in
  publication stage so should be out very soon.)

* Ensure the character data in localedata/charmaps/UTF-8 can be
  reproduced in some automated fashion from Unicode 6.0, locating any
  previously used automation for this or creating some new automation
  if any previous automation can't be found.

* Update the character data to Unicode 6.1, removing any local hacks
  in the automation from the previous step.

* Document thoroughly on the wiki how the automation works and how to
  do updates to new Unicode versions.
