Unicode filename support on Windows

[AlyoshaVasilieva]

Currently, attempting to optimize a file such as 「」.jpg gives error No compatible files found. Don't know if it works on Linux/OS X.

I've had a lot of trouble with this as well, it would be nice to have unicode support.

Looks like an old issue here. Attempting to affect files with accented characters results in "bad file" and files with other languages in them results in them being ignored entirely.

EDIT: Took a test run on Linux (Manjaro specifically) and it processed UTF-8 fine.

The issue is still here.
Since version 0.9.2 (switch from boost::filesystem to std::filesystem).
0.9.1 works fine.
