The first Issue 8 draft is focusing, afaik, on adding the C1x changes and Mantis Issue 8 tagged items. The changes to XBD 6, 7, etc., that will formally add a POSIX UTF8 locale are to be part of the second, maybe third, draft. This is why you don't see them yet. For maximum compatibility with existing practice the required base repertoire for this will likely be some subset of UCS-2, plus ISO-6429 in full, not the complete range. I've hopes this will be significantly more than the minimal repertoire of C2x, but it may not as a matter of deferral to the C standard. It should be left up to implementations still, in my opinion, how much of the range beyond this base they want to support as extensions, including UTF16 as an encoding. How the LC_* categories will be extended to fully support that base repertoire according to the Unicode requirements hasn't been determined yet either, but this is the nominal goal.

I wonder about POSIX.utf-?8, i tried to remember any statement i had read, and Mantis did not show up results. In particular i am interested in whether LC_CTYPE results will bring true Unicode support or not, the reason i am asking is that the upcoming version of my work-box GNU LibC-based (2.34) Linux distribution will provide it like localedef -i POSIX -f UTF-8 $PKG/usr/lib/locale/C.UTF-8 2> /dev/null || true and then this thing is detected as an UTF-8 locale, but causes three test failures of the MUA i maintain because character set conversion behaves differently. My personal opinion was that POSIX.utf8 will bring the complete range of Unicode characters to at least LC_CTYPE, i wonder about LC_COLLATE, as language matching is, hm, very language specific. The rest not (maybe LC_MESSAGES going for UTF-8 though). Is that approximately correct?
