Subject: bug#23: 23.0.60; Large Fonts with latin-1 characters inconsistent in size
Date: Wed, 27 Feb 2008 12:41:39 +0100

Please write in English if possible, because the Emacs maintainers
usually do not have translators to read other languages for them.

Your bug report will be posted to the emacs-pretest-bug <at> gnu.org mailing list.

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:

Editing a file in AUCTeX, I see the ugly screenshot shown below.  C-u
C-u C-x = on the (correctly sized_ character before the problematic
one delivers

        character: r (114, #o162, #x72)
preferred charset: ascii (ASCII (ISO646 IRV))
       code point: 0x72
           syntax: w 	which means: word
         category: a:ASCII graphic characters 32-126 (ISO646 IRV:1983[4/0])
		   l:Latin r:Japanese roman
      buffer code: #x72
        file code: not encodable by coding system iso-latin-1-unix
          display: by this font (glyph code)
     -Misc-Fixed-Medium-R-Normal--20-200-75-75-C-100-ISO8859-1 (#x72)

Character code properties are not shown: customize what to show

There are text properties here:
  auto-composed        t
  charset              iso-8859-1
  face                 (font-latex-slide-title-face)
  fontified            t

[back]


The same on the following (too small) Umlaut delivers:

        character: ä (228, #o344, #xe4)
preferred charset: gb18030 (GB18030)
       code point: 0x81308A31
           syntax: w 	which means: word
         category: j:Japanese l:Latin
      buffer code: #xC3 #xA4
        file code: #xE4 (encoded by coding system iso-latin-1-unix)
          display: by this font (glyph code)
     -Misc-Fixed-Medium-R-Normal--20-200-75-75-C-100-ISO8859-1 (#xE4)

Character code properties are not shown: customize what to show

There are text properties here:
  auto-composed        t
  charset              iso-8859-1
  face                 (font-latex-slide-title-face)
  fontified            t

[back]

The "code point" on the too small character looks somewhat ludicrous.
You can also see that apparently the same font is supposedly used.

I am pretty sure this did not happen pre-unicode2.  So what gives here?
