I don't know much about parameter modifiers in bash, but in zsh this
works for me:
title () {
1=${(%)1}
1=${(V)1}
1=${(q)1}
case $TERM in
screen*)
print -n "\ek$1\e\\" ;;
linux)
;;
*)
print -n "\e]2;$1\a" ;;
esac
}
The (%) modifier expands % escapes like in a prompt expansion (so %~
becomes the directory), (V) makes any special characters in the
resulting words visible (so a newline becomes \n) and the (q) modifier
quotes special characters with backslashes.
Don't know if this may help you.
