Font loading fails if font directory has unicode characters

[papr]

Well, bad news, @willpatera. This is an Windows problem only. It seems that fopen on Windows cannot handle utf-8 encoded char*... fopen call in fontstash

On Ubuntu, Pupil Capture loads font with unicode directories without problems.

So this is actually a https://github.com/memononen/fontstash issue . So I just made one: https://github.com/memononen/fontstash/issues/28

A note on attempting to fix this: We dont need to load a unicode file. We actually need to load a file with a unicode name/path -> world of pain: http://stackoverflow.com/questions/21402742/fopen-with-unicode-filename

This looks like something we should contract IMHO.

OK. I guess the task is to make a PR to fontstash and add this: https://github.com/Wohlstand/UTF8-fopen/blob/master/check.c

[mkassner]

this is fixed with https://github.com/memononen/fontstash/pull/37
