I'm trying to add SDL2TTF to my SDL project. I've successfully called SDL2 functions that take C-strings, but now I'm trying to call a function in SDL_ttf now, and it's crashing in what apparently is a UTF8 sizing operation:

	let font = TTF_OpenFont("Sans.ttf", 24)
	let textColor = SDL_Color(r: 255, g: 255, b: 255, a: 255)
	let text = TTF_RenderText_Solid(font, "Dec 10", textColor)    // Segmentation fault on macOS

Any idea what might be happening in here? Thanks.

Are you sure it's the UTF-8 string passing that's causing the issue in this case? Could the font returned by TTF_OpenFont be invalid/nil?

Ugh, I'm an idiot. I thought I had checked this but I hadn't. Let's fix that issue first. brb…
