Oh, sorry, I've posted it in a wrong place. Will move it to bugs.

Anyway, I've solved this problem by commenting out the .encoding() part:
- return locale.format("%d", val, grouping=True).decode(locale.getpreferredencoding())
+ return locale.format("%d", val, grouping=True)

Unsure whether this .decode() is needed and where this 0xc2 byte comes from - it's just a string containing a decimal number.
