Subject: Re: Re: a bug in bindtextdomain() and strip '.UTF-8'

no, it's on musl, i just tested it with my patches, with vim, stripping
will lead to unknown characters.
I mean, .mo files under zh_CN/ of vim is GBK set, while zh_CN/ of other
apps is UTF-8 set, that meas there may be other apps like vim, we should be
more cautious, add a check before map the .mo files, and fail non-UTF8 set
in setlocale.

Btw, _nl_msg_cat_cntr & _nl_domain_bindings will block apps compiling with
the native intl of musl, and after i added a dump for these two symbols,
gnu tar showed me segfaults, because he passed a zero msgid1 causing
__mo_lookup segfault, we should add a check in dcngettext to avoid it(if
(!msgid1) goto notrans;):

 #2  0x00007ffff7d82a6f in dcngettext (domainname=0x6737a0 "tar",
msgid1=0x0, msgid2=0x0, n=1,
    category=5) at src/locale/dcngettext.c:211
