PIL throws an OSError when it can't load a font

Possibly caused by non-Unicode characters in font path

Same issue after updating to Pillow 7.0.0

I have the same issue when using Windows 10 with Japanese and trying to open the font ARIAL.TTF

I'm using version 7.0.0 and handle dependencies with Poetry

PS C:\Users\Man\Documents\GitHub\crowd-ops\Projects\Add-Annotations>

I was able to find a work-around copying the file to the same folder as the script and then changing:

fnt = ImageFont.truetype("ARIAL.TTF", ANNOTATION_FONT_SIZE)

to

fnt = ImageFont.truetype("./ARIAL.TTF", ANNOTATION_FONT_SIZE)

Ok interesting, this seems to be a bit tedious to get going cross-platform. I'll investigate.
