I don't think Emacs has a mapping from the decomposed form back to the original character. You can look it up using ucs-names though: (defun lookup-composed (decomp) (let (composed) (maphash (lambda (key val) (when (equal decomp (get-char-code-property val 'decomposition)) ...


I think you want to M-x ucs-normalize-NFC-region RET


Personally I use the Multi_key (sometimes called the "compose" key) under X11, which I have mapped to the right Alt key. That works everywhere rather than only in Emacs.


I'm not sure about the feasibility of this. First, I believe this requires a backwards font on the system. I'm no expert on how text is actually rendered but, speaking generally, text is rendered using a "base description", such as a vector mapping. This base information is contained in a font file, such as a .ttf. Without some mapping, Emacs doesn't ...


I'm no expert on this, and this might not be the right way to do it, but I think this will do it for you: (define-key global-map (kbd "M-'") iso-transl-ctl-x-8-map))) iso-transl-ctl-x-8-map is a variable whose value is the keymap I think you're looking for, to bind to M-'. iso-transl-ctl-x-8-map is the value returned by this: (lookup-key key-translation-...


Most likely the font you are using probably does not display those characters well. (Does it work well when you use it outside Emacs?) Try using a different font.
