This is for Tinderbox, which uses the TextEdit text engine.
I have text that is already in there. It has two styles. The markup is smaller and grey while the marked text is dark red, almost black. A typical macro will have ten alternating zones.
(The markup is neither html or markdown, but it may be useful to think it were.)
I have the problem of curly quotes appearing. They appear in both styled areas.
The thing I want to accomplish is to straighten quotes and retain the style. At the moment, I copy to a named clipboard, apply a text factory and paste the result. The quotes are straight but the applied styles are gone. (The pasted result is all small grey.)
