Dear Emacs developers,
with this (see below) recently build emacs -Q -nw in an xterm /
urxvt (this does not happen in a graphical frame) enter this
Text:
Zwangsräumung von HG♿M99
The symbol between "HG" and "M99" is the unicode wheelchair symbol.
With point at the wheelchair symbol hit C-f: The cursor moves not to the
"M" but to the left "9". This gives problems in the rest of the line
when one for instance swaps characters with C-t. When doing so a few
times it's hard to tell if it's a display problem or if the letters are
swapped around.
The problem is also visible at the line between windows (see attached
screen shot). This happens when hitting C-l.
Is this an emacs bug, a terminal emulators bug or a bug of the font used?
Thanks for looking into this, Gregor
P.S.: Totally unrelated to this emacs problem: HG is a person who needs to use
a wheelchair, M99 is a shop in Berlin/Kreuzberg HG runs and in which he
also lives. His forcefull eviction is scheduled for 9th of August.
