That's the correct font, which is unexpected: the above
find-composition call is from describe-char, so if that returns the
correct font, how come describe-char winds up reporting an incorrect
font?
Could you perhaps step in Edebug through describe-char and see what
happens to the value returned by find-composition in your case, before
the font is reported? The call to find-composition is near the
beginning of describe-char, here:
(interactive "d")
(unless (buffer-live-p buffer) (setq buffer (current-buffer)))
(let ((src-buf (current-buffer)))
(set-buffer buffer)
(if (>= pos (point-max))
(error "No character follows specified position"))
(let* ((char (char-after pos))
(eight-bit-p (and (not enable-multibyte-characters) (>= char 128)))
(charset (if eight-bit-p 'eight-bit
(or (get-text-property pos 'charset)
(char-charset char))))
(composition (find-composition pos nil nil t)) <<<<<<<<<<<<<<<
(component-chars nil)
Thanks.
