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

If its idea of a control glyph is different than your own, then
you'll have to look to modifying the NSGlyphGenerator.
Hmmm....
Well, like Dominik (http://www.cocoabuilder.com/archive/message/
cocoa/2006/4/10/160743), I don't see any layout change, but the
methods are being called appropriately.

I guess I'll have to try the glyph generator...?
Of course you can't subclass NSGlyphGenerator because it's an
abstract class so you need to fully implement the generateGlyphs
method and I hardly have any clue as to what I'm doing, so this is no
fun.
actionForControlCharacterAtIndex tooooooootally should work but I
can't figure out why it doesn't. Returning
NSTypesetterHorizontalTabAction works as you'd expect, but
NSTypesetterWhitespaceAction doesn't. I've searched all over, docs,
google, mailing lists, the header, and read every single thing I
could find and nothing is offering any hints. Bah.
