We have had one downstream report from Canonical [1] that
an rrdtool test was broken by the differences in LC_TIME
that we had in the non-builtin C locale (C.UTF-8). If one
application has an issue there are going to be others, and
so with this commit we review and fix all the issues that
cause the builtin C locale to be different from C.UTF-8,
which includes:
* mon_decimal_point should be empty e.g. ""
- Depends on mon_decimal_point_wc fix.
* negative_sign should be empty e.g. ""
* week should be aligned with the builtin C/POSIX locale
* d_fmt corrected with escaped slashes e.g. "%m//%d//%y"
* yesstr and nostr should be empty e.g. ""
* country_ab2 and country_ab3 should be empty e.g. ""
We bump LC_IDENTIFICATION version and adjust the date to
indicate the change in the locale.
A new tst-c-utf8-consistency test is added to ensure
consistency between C/POSIX and C.UTF-8.
Tested on x86_64 and i686 without regression.

We add a new C.UTF-8 locale. This locale is not builtin to glibc, but
is provided as a distinct locale. The locale provides full support for
UTF-8 and this includes full code point sorting via STRCMP-based
collation (strcmp or wcscmp).
The collation uses a new keyword 'codepoint_collation' which drops all
collation rules and generates an empty zero rules collation to enable
STRCMP usage in collation. This ensures that we get full code point
sorting for C.UTF-8 with a minimal 1406 bytes of overhead (LC_COLLATE
structure information and ASCII collating tables).
The new locale is added to SUPPORTED. Minimal test data for specific
code points (minus those not supported by collate-test) is provided in
C.UTF-8.in, and this verifies code point sorting is working reasonably
across the range. The locale was tested manually with the full set of
code points without failure.
The locale is harmonized with locales already shipping in various
downstream distributions. A new tst-iconv9 test is added which verifies
the C.UTF-8 locale is generally usable.
Testing for fnmatch, regexec, and recomp is provided by extending
bug-regex1, bugregex19, bug-regex4, bug-regex6, transbug, tst-fnmatch,
tst-regcomp-truncated, and tst-regex to use C.UTF-8.
Tested on x86_64 or i686 without regression.
