Package: xterm
Version: 4.3.0.dfsg.1-6
Severity: normal
In the en_US.UTF-8 locale, inserting any non-ascii character into the c=
ommand
line and then backspacing over it seems to backspace over bytes rather th=
an
characters. If I insert "=C3=A1=C3=B5=C3=A3" (either with compose keys o=
r by cut-and-paste),
I can then backspace over the last few characters of my prompt:
[moise@pogo ~]$
[moise@pogo ~]$ =C3=A1=C3=B5=C3=A3
[moise@pogo ~]$ =C3=A1=C3=B5
[moise@pogo ~]$ =C3=A1
[moise@pogo ~]$
[moise@pogo ~]$
[moise@pogo ~=EF=BF=BD
Also, if I type "ls=C3=A3" and then backspace one time, I get "zsh: com=
mand not
found: ls\M-C" when I hit enter.
This only happens with zsh (not bash), so it could easily be a zsh bug.=
It
doesn't happen with aterm or on the console, though, so I've arbitrarily =
filed
the bug against xterm :-).
Just like #266336, this happens with both xterm and "xterm -class UXTer=
m
-title 'uxterm' -u8" (the guts of uxterm) when LANG and LC_ALL are en_US.=
UTF-8,
and not with either with en_US.ISO-8859-1.

No problem. Thanks for the swift follow-up!
Closing as not-an-xterm-bug per submitter and upstream maintainer.
Anyone reading these logs should see #205651 for more information.
