Arabic uses automatic compositions, not static compositions produced by text properties. If you want to see which scripts use the 'composition' properties, search Lisp files for compose-region. Perhaps Handa-san could tell if having 'composition' properties in comments and strings is something that can happen in real life for some scripts used in those comments/strings. If it can (and I don't know one way or the other), then I don't think we should remove all of the 'composition' properties just because font-lock was turned off. > we're still a long way from another release, I suppose.

But that assumption is not really guaranteed to be true.
