I'm pretty sure "No" was the best answer. ;-)
Also, whatever that command is supposed to be, it doesn't work as
written in bash 4.3 on HP-UX:
$ printf -v x %s%n $'\uE4' lx; head -c "$lx" <<<"$x"; echo " b"
4: No such file or directory
b
imadev:~$ declare -p x lx
declare -- x="\\uE4"
declare -- lx="4"
