Great, thanks.

I don't think it's a bug. It's likely just an issue with the font(s)
you are using If you insert this pair of codepoints in a buffer, can
you move point between them with C-f and C-b? If you can, it means
they are not composed for some reason, perhaps the font you are using
doesn't have a glyph for the acute accent, so Emacs uses a different
font for it, and thus is unable to compose. Try a different font.
