Not from within emacs, only if it is set as an environment variable.
The locale is reset again to the environment when gstreamer is
initialized, which is likely a bug in gstreamer.  The main window is
already mapped at that time and the command loop is running.

The proper fix is likely to not bother with fixup_locale at all in its
current form, but either implement the lisp reader without
locale-dependent functions or getting a locale object on entry, change
the locale, do whatever it needs to do under changed locale and then
restore the locale.  This is what libraries are often doing for parsing
configuration files, anyway.

There are also some hints that glib expects / recommends to call
setlocale, textdomain, bind_textdomain and bind_textdomain_codeset early
in main on order to properly initialize it.


Regards,
Achim.
