That doc string has been around since at least Emacs 22. Then I don't understand what else do you want to know about compose-region and character composition in general. > I would expect some conceptual explanation of character composition > in the Elisp manual. Please start by explaining what is missing from the doc string of compose-region, because otherwise it is impossible to translate your expectation to any concrete text. The example you gave in the bug report is not about character composition, it's about font-lock. So maybe that is what you need to be explained. However, the bug report says "character composition", so until you agree it's about something else, "character composition" it is. > Including how to decompose composed chars etc. You can't. This question makes no sense. Character composition converts several characters into one or more glyphs to be displayed; you cannot "decompose" them, and in any case the result of such decomposition is known in advance: they are the original characters. > What the bug report mentions. I don't think that a doc string for > one command covers this topic. Well, I think it does. You could change my mind by telling what is it that you miss in that doc string.
