Why not do away with the fragile binary characters here and instead do:

function settitle() { echo -ne "\e]2;$@\a\e]1;$@\a"; }

Or the simpler:

function settitle() { echo -ne "\e]0;$@\a"; }

I actually use the following, which sets the title via the prompt (which
means it's more persistent):

function settitle()
{
    if [ $# -eq 0 ]
        then
        eval set -- "\\u@\\h: \\w"
    fi

    case $TERM in
        xterm*) local title="\[\033]0;$@\007\]";;
        *) local title=''
    esac
    local prompt=$(echo "$PS1" | sed -e 's/\\\[\\033\]0;.*\\007\\\]//')
    PS1="${title}${prompt}"
}

With this, it's nice to do:

$ PS1="\u\$ "
$ settitle "\\h: \\w"

This puts the user name in the prompt, and the host and working directory
in the title bar.
