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
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?

yes, that would be appreciated, thanks.
