Description Benno Schulenberg 2007-05-04 21:44:00 UTC
For now I can only reproduce this when the hostname is 3, 4, 5 or 6 characters long, and the directory name 9, 10 or 11 characters long.

Try setting PS1='\[\e[1;32m\]xxyyzz \[\e[1;34m\]\w \$\[\e[0m\] ', then 
mkdir ĉaĉaĉaĉaĉ, cd ĉaĉaĉaĉaĉ, ls somefile, ^R so

See attached typescript for an example.  I've unset PROMPT_COMMAND to get rid of the extra output.  This is on a Konsole, with Encoding set to Unicode (utf8).

Sorry, vapier, this is not a duplicate.  The other bug is about colours in the PS1 prompt (with any type of characters), this is about multibyte characters in the directory name (while any colour is irrelevant).  Here is a simpler recipe:

PS1='xxyy \W \$ '
mkdir ĉaĉaĉaĉaĉa
cd ĉaĉaĉaĉaĉa/
ls somefile
^R so

Yes. This is completely different issue. I've just sent my observations upstream and hope Chet will fix this soon.

you can retry with 3.2_p33 as it has some invisible byte fixes
