Re: Integer & glyph (trunk and emacs_unicode)

[Richard Stallman]

        (let ((id (and face (face-id face))))
          (if (and (numberp id)
                   ;; Due to limitations on Emacs integer values, only
                   ;; face ids below a certain limit can be used.
                   (= id (lsh (lsh id glyph-char-bits) (- glyph-char-bits))))
              (logior char (lsh id glyph-char-bits))
            char))

    Is there any problem if I implement this solution in trunk and Emacs 
    unicode?

It's not _wrong_, but we've already decided to replace the
mechanism with the use of cons cells.

And I am pretty sure someone has already written the code for that.
Who was it?
