Hi Harald,
the locale setting is only for the current program.
And as indicated,
at least so far, most libosmocore users are single-threaded, i.e. nobody
would notice if the locale was different for a very short amount of
time. Furthermore, assuming that the code is not called all that often
(i.e. only once at program startup) I wouldn't be worried about that so
much.
I can add some kind of global var which will indicate UTF-8 support
and init it when app starting with code above (or other code if will
find better one). Then use it in case of SMS/USSD receving.
I am not an expert in locale.h matters, but it would
somehow be strange
to me if you cannot determine utf-8 support without having to actually
change the locale. Is anyone on this list more familiar with it?
I asked some time
ago, but there was no answer.. setlocale function
with NULL argument always returns "C" - Minimal "C" locale - if
locale
was not changed before, with arguments rather than NULL - changes the
locale.
Thanks,
Pavel
