Please take a look at http://bugzilla.xfree86.org/show_bug.cgi?id=544 and
Since there are a lot of free almost-full supported ISO10646 fonts in Linux,
like unifont, xfonts-efont-unicode and xfonts-wqy.
(You may find them in Debian)
So I think that all of XLC_LOCALE for UTF-8 should be prior to use ISO-10646
earlier than ISO8859-1.
Please consider to recover it. Thanks.
AFAIK, at least ja_JP.UTF-8 and zh_TW.UTF-8 are broken.
Sorry about the phenomenal bug spam, guys. Adding xorg-team@ to the QA contact so bugs don't get lost in future.
Downstream closed this as fixed, so I'm assuming it is fixed here. Please
reopen if this is still an issue.
