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

Hello!

I have a file named

	RGB äöüæÆÜÖÄ.txt

it gets displayed as

[pastedGraphic.tiff (image/tiff, inline)]

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

The ominous capital C with lowered diaeresis is described as:

I don't see any bug here; the accents are displayed on the top of the
character.  Could you check again with latest CVS and see if the problem
persists?

What you cite (and see) is what I wrote as the *text* of the file's  
name. I cannot copy and paste the *representation* GNU Emacs then  
chose – except as a photograph/screen-shot.

With GNU Emacs from one or two days ago it looks a bit better, like  
this:

[Emacs Umlaute.png (application/applefile, inline)]

[Emacs Umlaute.png (image/png, inline)]

[Message part 4 (text/plain, inline)]

As you can see it uses for R, G, B, SPC, æ, Æ, ., t, and x the  
correct font:

          display: by this font (glyph code)
    x:-b&h-lucidatypewriter-medium-r-normal-sans-10-100-75-75-m-60- 
iso10646-1 (#x52)

For ä I get:

          display: composed to form "ä" (see below)

Composed with the following character(s) "¨" using this font:
  x:-mutt-clearlyu-medium-r-normal--17-120-100-100-p-123-iso10646-1
by these glyphs:
  [0 1 97 97 7 1 7 7 0 nil]
  [0 1 776 776 0 0 5 14 -12 [-5 3 0]]

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

(The non-spacing ¨ is faked here with a spacing one. The *Help*  
buffer uses the COMBINING DIAERESIS U+0308 from ClearlyU. Lucida  
Typewriter does not have this glyph.)

It would be better GNU Emacs would compose the de-composed characters  
and then use the glyphs from the default font.

(That was 11 years ago.)

I'm unable to reproduce this.  All characters seem to display
correctly.

Are you still seeing this on a modern version of Emacs?  If I don't
hear back from you within a couple of weeks, I'll just close this bug
as unreproducible.

Best regards,
Stefan Kangas

I checked with a few GNU Emacs versions. Even version 23.4 handles the umlauts in file names correctly.

Theory and practice are the same, in theory, but, in practice, they are different.

Thanks for verifying.  I'm consequently closing this bug.
