But what to do if I want do make room to display an invisible character/glyph? Is there any way to dynamically add an advancement to an otherwise unadvancing invisible? e.g. ASCII 11? This has to be dynamically show invisibles can be turned on and off.

One possible solution would be a custom glyph generator to substitute a visible glyph for NSControlGlyph. Another would be a custom typesetter implementing actionForControlCharacterAtIndex: and boundingBoxForControlGlyphAtIndex:forTextContainer:proposedLineFragment: glyphPosition:characterIndex:.
