Programs like `ls' honor the LC_COLLATE environment variable. Emacs
shall do it as well. This shouldn't affect only directory listings, but
could be used also for string searches.

Maybe we should expose glib's g_utf8_collate() on Lisp level. On systems
without glib, we might emulate it partially. Packages like ls-lisp could
use it then for sorting.

I have no clear forecast on my time budget next weeks. If possible, I
would play with this.

Best regards, Michael.
