Bash prompt wrap broken when path has unicode (Greek) characters

When a path is too long to fit on the terminal and it wraps, the following prompt is broken and you can't see properly what is typed. See screenshot below: These are the contents of .bashrc that set the PS1, which is the default provided by Ubuntu. if [ "$color_prompt" = yes ]; then PS1='${debian_chroot:+($debian_chroot)}\[\033[01;32m\]\u@\h\[\033[00m\]:\[\033[01;34m\]\w\[\033[00m\]\$ ' else PS1='${debian_chroot:+($debian_chroot)}\u@\h:\w\$ ' fi unset color_prompt force_color_prompt # If this is an xterm set the title to user@host:dir case "$TERM" in xterm*|rxvt*) PS1="\[\e]0;${debian_chroot:+($debian_chroot)}\u@\h: \w\a\]$PS1" ;; *) ;; esac The value of $PS1 is echo "$PS1" \[\e]0;\u@\h: \w\a\]${debian_chroot:+($debian_chroot)}\[\033[01;32m\]\u@\h\[\033[00m\]:\[\033[01;34m\]\w\[\033[00m\]\$ Is there any way to fix it? I have seen several other similar questions, and the proposed solution is to enclose the offending part in \[ \], or to set checkwinsize, but neither worked in my case. If anyone wants to test with the path, it is the folowing: /home/dimitriv/Dropbox/personal/kastoria/2018-2019/προγραμματισμός στο διαδίκτυο/newslides
