Failure to show "German Umlaute"

[Joachim Reiter]

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 bug-gnu-emacs@gnu.org mailing list,
and to the gnu.emacs.bug news group.

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

1. Starting Emacs
2. 'M-x Gnus' to start Gnus
3. I.E. I would to read de.comp.editoren I press <SPACE>, if the Cursor
is in Group-Summary over this Group
4. At first, I see the failure in Subject, so it has 'German Umlaut',
later in Article-Summary too

The failure only is shown, so a 'German Umlaut' is together used with
'mö' also 'wö', for this Example by the 'm' also the 'w' the right edge
of the Letters (m + w) shown 'cutted' - If I click one of the Letters
with Mouse, so the Cursor is on it, the look is OK, if I click another
one, the failure will return.

So it looks like, the 'German Umlaut' over-paint the 'm' or the 'w' by
edge.

I attached a Test-Case and the result of 'M-x describe-char RET' by
using the 'm' with 'ö', 'm' with 'o', 'w' with 'ö', 'w' with 'o' the 'ö'
and the 'o'.
Also I send a Text-file with a small Text including the Letters making
the failure also them without failure.

For looking, how its shown by me, look at followed Links so you can see
this too...
