Segfaults when loading fonts with special characters in filename.

[rootino]

Using RFont_font_init on filenames which contain hyphens such as "Roboto-Regular.ttf" causes immidate segfault.

Could you give any information of where this happens? What OS for instance.

Considering I have tested fonts with hyphens, NotoEmoji-Regular.ttf is included. This makes me think that is more likley that your font has not been found rather than it being caused by an abitrary symbol.

After a quick test this seems to be the case. RFont should probably be doing asserts and other checks to prevent random crashes like this.

[ColleagueRiley]

I added those checks in this PR. #22

Your test should now through an assert instead of crashing randomly.

lol

Forgive me, when opening this I had narrowed down a segfault to the font init function and it was happening consistantly when changing between two identical font files: Roboto-Regular.ttf and roboto.ttf (same file but renamed), but upon attempting to recreate the same scenerio again today i could not successfully replecate my issue.
