Font problem with emacs-23.1

Font problem with emacs-23.1

[Peter Münster]

Hello,

I use the font
-efont-fixed-medium-r-normal--24-240-75-75-c-120-iso10646-1
in emacs.

No problem with version 22.3, but after the update to 23.1, some characters
look very strange:

Do you know, how to get ü, ß, à, è and é displayed correctly?

TIA for any help!
Cheers, Peter

What does Emacs show if you go to one of these strangely displayed
characters and type "C-u C-x ="?  And how does that differ from what
Emacs shows for the characters that are displayed correctly?

Hello Eli,

Here is the output of this command for "ö":

        character: ö (246, #o366, #xf6)
preferred charset: unicode (Unicode (ISO10646))
       code point: 0xF6
           syntax: w 	which means: word
         category: .:Base, j:Japanese, l:Latin

          display: by this font (glyph code)
    xft:-Efont-Efont Biwidth-normal-normal-normal-*-24-*-*-*-d-120-iso10646-1 (#xB6)

  decomposition: (111 776) ('o' '̈')

There are text properties here:
  fontified            t

-------------------------------------------

And here for "é" (one of the strangely displayed characters):

        character: é (233, #o351, #xe9)
preferred charset: unicode (Unicode (ISO10646))
       code point: 0xE9
           syntax: w 	which means: word

And here for a normal ASCII character:

        character: a (97, #o141, #x61)
preferred charset: ascii (ASCII (ISO646 IRV))
       code point: 0x61

          display: by this font (glyph code)
    x:-efont-fixed-medium-r-normal--24-240-75-75-c-120-iso10646-1 (#x61)

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

There are text properties here:
  fontified            t

-------------------------------------------

Unfortunately, I don't understand much of that information...

Does anybody can reproduce this problem?
I'm using Xorg-7.4 on openSUSE-x86_64.

Cheers, Peter

As you see, Emacs uses two different fonts to display these two
characters.  Maybe the font
"-Efont-Efont Biwidth-normal-normal-normal-*-24-*-*-*-d-120-iso10646-1"
does not support é and the other characters that look strangely?

This font worked fine in GNU Emacs 22.3...

Anyway, it's worth to check the two fonts to see what they actually  
offer (FontForge or GNU Charmap etc.). Another solution is to create  
a fontset in which for each encoding a specific (the same) font (with  
in the case of 7- or 8-bit encodings this font's specific font  
encoding is given, i.e., -iso8859-X, -koi8-Y, -microsoft-cp1252, -ibm- 
cpXYZ) is specified to stop GNU Emacs 23 from making its own faulty  
choice.

Indeed.

I don't know, why emacs chooses this font for the letter ö and the
-efont-fixed-medium-r-normal--24-240-75-75-c-240-iso10646-1 font
for the letter é.

But now, I've found the solution (by trial and error without
understanding):

emacs -fn "-efont-efont biwidth-medium-r-normal--24-240-75-75-d-120-iso10646-1"

This font works quite well, only the splash screen is ugly: no logo and no
colors, but it doesn't matter for me.

And: this font is *not* listed by xlsfonts...

Cheers, Peter

(require 'ucs-normalize) ?

Hello Peter,

Unfortunately this does not help. But the start-up of emacs takes now
30 seconds!
