Data model -> View model -> View But since you want to edit it, it is probably too cumbersome. Of your two suggested approached I think the QTextLayout has the best chance of working. One of the problems with QTextEdit is that it is a rich text editor, so it will collapse white spaces in rich text mode, and probably collapses zero- space whitespace even in plaintext mode. Which means if you replace the font, the zero space characters could already be handled an never looked up in the font. I would look up how QtCreator and KWrite handles emoticons, and similar fancy text tricks. Emoticons are when text smileys : ) are replaced at editing time with emojis. This type of replacement sounds similar to what you need.
