Title: _localemodule.c: str2uni() with different LC_NUMERIC and LC_CTYPE

Oh, I just realized that the issue is a LC_NUMERIC using an encoding A with a LC_CTYPE using an encoding B. It looks like the glibc does not support this setup, at least for the fi_FI locale which has a non-ASCII thousand separator (non-breaking space: U+00A0).

Try attached inconsistent_locale_encodings.py script (it uses locale names for Fedora 19, you may have to adapt it to your OS).


Output on Fedora 19:
