Display problem with upper case accentuated chars

Display problem with upper case accentuated chars

[Vinicius Jose Latorre]

I'm having display problem with upper case accentuated chars when using 
Emacs 21.3.50.1.

I'm using GNU Emacs 21.3.50.1 (downloaded and installed today - 
2003-06-07) and Red Hat 8.0.

The problem is that when I insert, for example, the character à in a 
buffer, it is displayed:

Ä   Ã
 ^
 |
 +---- here is where the cursor is positioned after insertion

The characters À, Á, É, Í, Ó and Ú are displayed with a 'point' above 
the letter instead the proper accent.

The characters Ã, Õ and Ê are displayed Ä, Ö and Ë, respectively.

The problematic characters that I found are:

CHAR   TYPING C-x =
À      (04300, 2240, 0x8c0, file C0)
Á      (04301, 2241, 0x8c1, file C1)
à     (04303, 2243, 0x8c3, file C3)
É      (04311, 2249, 0x8c9, file C9)
Ê      (04312, 2250, 0x8ca, file CA)
Í      (04315, 2253, 0x8cd, file CD)
Ó      (04323, 2259, 0x8d3, file D3)
Õ      (04325, 2261, 0x8d5, file D5)
Ú      (04332, 2266, 0x8da, file DA)

The lower case characters are ok.

It seems that they are displayed with such a font that the
font's glyphs are taller than the font's logical bounding
box.  Thus the topmost few pixels are overwritten by the
previous line.  That also explains why lowercase characters
are ok.

Please type C-u C-x = on problematic characters and check
what fonts are used.

Ok, below are the results of C-u C-x =.

Well, I also notice the following:

* I inserted the characters in *Scratch* buffer and notice that if the
  character is inserted in the first buffer position, the character is
  displayed ok.  But it is not ok if inserted in any other place.

* The *Help* buffer, displayed after typing C-u C-x =, shows the character
  without any problem.  But when I copy and paste into another buffer, the
  problem appears.

I confirmed that this bug is reproducible by the above font.

I also found that this problem didn't happen in the version
before 2003-5-24 but happen in the version just after
2003-5-24.  So, I suspect that the big change on 2003-5-24
introduced some bug.

Kim?  Could you investigate this problem?

Another info.  If I set fringe-mode to none, this problem
doesn't happen.

I'm seeing a similar display problem: accentuated upper case characters
are displayed one screen position to the right, and the same character but
with a different accent is displayed instead on the real position.  Only
the characters with an umlaut accent are displayed correctly.  I'm using
the font -Adobe-Courier-Medium-R-Normal--14-100-100-100-M-90-ISO8859-1.

I inserted (fringe-mode 'none) in my .emacs file, but the problem still 
persits.

I have a pretty good idea what the problem is... and how to fix it.

Stay tuned :-)
