Re: How to insert a screen-only character in an NSTextView?
This would be better handled with some sort of filter applied at I/O time (i.e. when you read/write the file) I would think. That is, let your model objects handle the translation, and let the view objects do what view objects are supposed to do. 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!

Keep in mind that one character can generate multiple glyphs, especially since doing this seems to be why you started this thread in the first place. This is important, since characters have no visual attributes whatsoever; all drawing and metrics are done in terms of glyphs. I thought I need to control that with setting the size of a textcontainer? You do indeed need to set the width of the text container.
