Trying to fiddle around with low-level NSTextStorage just seems to be a way to waste several afternoons pulling out your hair in frustration, methinks!
I disagree. NSTextStorage *is* a model object. It's far better to actually understand and and use the text system (including glyph generation) rather than "fake it" by transforming the model on read/write and ensuring your transformations are perfect mirrors, are applied at the right times, and correctly interact with the pasteboard, undo manager, Services, Input Methods, and VoiceOver.
