But with many invisible characters (like, all others - the null character for example), they have no width at all, so drawing a character at the location where they normally would be just draws on top of the next character.


You'll want to create an NSTypesetter subclass that overrides:

- actionForControlCharacterAtIndex:
- boundingBoxForControlGlyphAtIndex:etc:

If its idea of a control glyph is different than your own, then you'll have to look to modifying the NSGlyphGenerator.
