  Right, I'd forgotten that.  We're bound by the libc locales.  Too bad
they don't support script codes.

  I remain convinced that people wouldn't use zh_CN and zh_TW for
Simplified Chinese and Traditional Chinese, respectively, if you could
specify a script name in the locale.  For some languages, you really
need this, like Serbian, for instance.  I also wonder if, for example,
zh_SG falls back to zh_CN if the system doesn't support the former.

  If I'm not mistaken, ICU uses RFC 4646 tags for its locale codes, but
that's of course a special project.
