[Message part 1 (text/plain, inline)]

Hello!

In *Buffer List* one file name is written completely in my default font:

    Lüfter                  36  Fundamental	  ~/Lüfter
    Übersicht              959  Fundamental	  ~/Documents/Musik/ 
Nachtmix/Übersicht

        character: Ü (220, #o334, #xdc)
preferred charset: iso-8859-1 (Latin-1 (ISO/IEC 8859-1))
       code point: 0xDC
           syntax: w 	which means: word
         category: .:Base, j:Japanese, l:Latin
      buffer code: #xC3 #x9C
        file code: #xC3 #x9C (encoded by coding system utf-8-unix)
          display: by this font (glyph code)
    x:-b&h-lucidatypewriter-bold-r-normal-sans-10-100-75-75-m-60- 
iso8859-15 (#xDC)

  name: LATIN CAPITAL LETTER U WITH DIAERESIS
  general-category: Lu (Letter, Uppercase)
  canonical-combining-class: 0 (Spacing, split, enclosing,  
reordrant, and Tibetan subjoined)
  decomposition: (85 776) ('U' '̈')

There are text properties here:
  buffer               #<buffer Übersicht>
  buffer-name          "Übersicht"
  font-lock-face       buffer-menu-buffer
  help-echo            "mouse-2: select this buffer"
  mouse-face           highlight

        character: Ü (220, #o334, #xdc)
preferred charset: iso-8859-1 (Latin-1 (ISO/IEC 8859-1))
       code point: 0xDC
           syntax: w 	which means: word

while in another files' or buffers' names the lower case ä or  
capital Ü are taken from a different font although they also exist in  
the default font:

    Kanäle                6905  Fundamental	  ~/Kanäle
    Jabberwock.java       1059  Java/l		  ~/Im Übrigen/ 
Jabberwock.java

        character: a (97, #o141, #x61)
preferred charset: ascii (ASCII (ISO646 IRV))
       code point: 0x61
           syntax: w 	which means: word
         category: .:Base, a:ASCII, l:Latin, r:Roman
      buffer code: #x61
        file code: #x61 (encoded by coding system utf-8-unix)
          display: composed to form "ä" (see below)

Composed with the following character(s) "̈" using this font:

  help-echo            "mouse-2: select this buffer"
  mouse-face           highlight


The attached screen-shot also shows that in pop-up menu some  
characters are displayed as decomposed UTF-8 characters (the ä in  
Kanäle becomes a¨) while others are converted to their byte  
sequences (ü in Lüfter and Sprüche is converted to C3 BC which are  
displayed as ü).

Is this still a problem in a current Emacs?

When you mean with "current" GNU Emacs 23.3, then it's yes. In the Motif variant I can see this:

[23.3.png (image/png, inline)]

[Message part 3 (text/plain, inline)]

The original names are: "Hübsche Tagebucheinträge" and "RGB äöüæÆÜÖÄ.txt". In GNU Emacs 24.0.50 the problem is solved, even decomposition of accented characters as in Apple's HFS+ is solved.

Right.  I think the likelihood of this being fixed in Emacs 23 is pretty
slim, but since it's fixed in Emacs 24, I'm closing this report.
