Hi,

since r59163 I am getting following error when GRASS 7 is started. I am

Comment:

Ahh. I see. The new language override code is too tolerant - if no
override is specified, it doesn't call setlocale() at all and thus process
ends running with C locale.

Should be fixed in r59211. Reopen this bug if needed.

Try r59215. I changed a bit enforcing of locale on GRASS process and also
worked-around gettext on Windows issue (it fails to load default locale
translations as Windows doesn't set LANG by default).

Comment(by marisn):

I'm not able to reproduce the issue on my system no matter how hard I try.

Still the issue seems to be twofold - there was not robust enough code to
set language/locale in startup script. It is fixed and from r59215 it
should work just fine* The second problem is that now some problems with
other wxgui code have popped-up. I.e. getdefaultlocale shouldn't be used
to get encoding.

Can you, please, apply this patch and give me back output?

Can you, please, test after r59652? I added some extra care to the cases
when Python fails to detect default locale. Generally it indicates on some
kind of problem with system's locale.
