Simple question, to which I've found a multitude of ridiculously complex
answers in the archives. I just want the Bezier path of a character, e.g.,
"A", "?", "&".
[path appendBezierPathWithGlyph:(NSGlyph)something(@"A")
infont:[NSFont systemFontOfSize:400];
There must be a simple function "something" that will map the glyph
index of a given character. What is it?
