OSX: CGGlyph to UniChar

Question

I am currently writing a simple bitmap font generator using CoreGraphics and CoreText. I am retrieving the kerning table of a font with:

CFDataRef kernTable          


        

Answer 1

I don't know a direct method to get the Unicode for a given glyph, but you could build a mapping in the following way:

• Get all characters of the font with CTFontCopyCharacterSet().
• Map all these Unicode characters to their glyph with CTFontGetGlyphsForCharacters().
• For each Unicode character and its glyph, store the mapping glyph -> Unicode in a dictionary.
