[issue34752] warnings.warn fails silently with unicode input

I think this a known limitation as per https://bugs.python.org/issue23637#msg239361 where non-ASCII characters would require byte string. I couldn't find the relevant documentation for it though.

$ ./python.exe
Python 2.7.15+ (remotes/upstream/2.7:69d0bc1430, Sep 24 2018, 16:02:09)

Type "help", "copyright", "credits" or "license" for more information.
>>> import warnings
>>>
>>> warnings.warn(b'blé')
__main__:1: UserWarning: blé
>>> warnings.warn(u'blé')
>>>

Thanks
