still `umlaut-bug' with current Emacs

Ken'ichi,


using a CVS build from about 24h ago, I still see the problem with
diacritical characters taken from another font.  In the attached
image, the blue font is

  -sony-fixed-medium-r-normal--24-170-100-100-c-120-iso8859-1

while the large `umlaut U' is

  -monotype-Arial-bold-normal-normal-*-32-*-*-*-*-0-iso10646-1

Here is the minimal `.emacs' file to reproduce the problem:

  (defvar fontset-24
    "-*-fixed-medium-r-*-*-24-*-*-*-*-*-fontset-24")

  (create-fontset-from-fontset-spec fontset-24)

  (setq default-frame-alist
          '((font . "fontset-24")))

  (require 'tex-site)
  (require 'tex)

Note that my fontconfig engine is configured to return bitmap fonts
also.

I forgot to mention that I was loading a TeX file, of course, using
AUCTeX version 2009-03-22.

With exactly the same setup I see another bug, as shown in the
attached image.  The displayed text should be

  \textit{%
    xxx \textbf{yyy}\\
    zzz}

`C-u C-x =' says this for the first `y' character:

          character: y (121, #o171, #x79)
  preferred charset: ascii (ASCII (ISO646 IRV))
         code point: 0x79
             syntax: w 	which means: word
           category: .:Base, a:ASCII, l:Latin, r:Roman
        buffer code: #x79
          file code: #x79 (encoded by coding system utf-8-unix)
            display: no font available

  Character code properties: customize what to show
    name: LATIN SMALL LETTER Y
    general-category: Ll (Letter, Lowercase)

  There are text properties here:
    face                 (font-latex-bold-face font-latex-italic-face)
    font-lock-multiline  t
    fontified            t

Somehow mew's encoding recognition failed.  The `Ãœ' is of course `Ü'
in UTF-8.

I've just installed a fix.  Please try again.

I can't reproduce it.  What does C-u C-x = say on the
character "x"?

This works now, thanks.

I still get it.

Using CVS emacs from today, it works now.  Thanks for fixing!
