Then I don't understand what else do you want to know about
compose-region and character composition in general.

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.

Well, I think it does. You could change my mind by telling what is it
that you miss in that doc string.
