Re: [Enigma-devel] Locales

[Erich Schubert]

Hi Andreas,
The relevant part of the patch is attached.
(The other parts were to make sure system-gettext is used, not the
code included in enigma).

I exploit that setlocale returns NULL when the locale is not available:
if (setlocale (LC_MESSAGES, val) != NULL)
then I just retry with locale + ".UTF-8"

Regards,
Erich
