Public bug reported: An UTF-8 character after an Ascii character is misinterpreted. It's difficult to explain the trouble so I get some commands to actually see it. Feel free to improve my description.
This test case work on gnome-terminal and xterm only when it is sized with 80 characters long. $ echo $PS1 # Default value \[\e]0;\u@\h: \w\a\]${debian_chroot:+($debian_chroot)}\u@\h:\w\$ $ temp_dirname1=/tmp/$(perl -e 'print "a" x '$(echo "80-(${#USER}+${#HOSTNAME}+4)-4" | bc)',"à","a" x 4,"\n"') $ temp_dirname2=/tmp/$(perl -e 'print "a" x '$(echo "80-(${#USER}+${#HOSTNAME}+4)-4" | bc)',"a","a" x 4,"\n"') $ temp_dirname3=/tmp/$(perl -e 'print "a" x '$(echo "80-(${#USER}+${#HOSTNAME}+4)-5" | bc)',"àà","a" x 4,"\n"') $ echo -e $temp_dirname1"\n"$temp_dirname2"\n"$temp_dirname3 # Look at the actual values for these three variables $ mkdir $temp_dirname1 $temp_dirname2 $temp_dirname3 $ cd $temp_dirname1 # Wrong display $ cd $temp_dirname2 # Correct display $ cd $temp_dirname3 # Neither completely correct display neither wrong display (there is one space left at the end of the line that doesn't exist) ProblemType: Bug DistroRelease: Ubuntu 13.10 Package: bash 4.2-5ubuntu3 ProcVersionSignature: Ubuntu 3.11.0-12.19-generic 3.11.3 Uname: Linux 3.11.0-12-generic i686 ApportVersion: 2.12.5-0ubuntu2.1 Architecture: i386 Date: Mon Nov 4 15:04:59 2013 InstallationDate: Installed on 2013-04-22 (195 days ago) InstallationMedia: Ubuntu 13.04 "Raring Ringtail" - Release i386 (20130420) MarkForUpload: True SourcePackage: bash UpgradeStatus: Upgraded to saucy on 2013-09-06 (59 days ago) ** Affects: bash (Ubuntu) Importance: Undecided Status: New ** Tags: apport-bug i386 saucy -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1247854 Title: PS1: wrong display of accentuate character with \w To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/bash/+bug/1247854/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
