I use this function to URL-encode things in zsh:

    function url-encode() {
      emulate -L zsh -o extended_glob
      local MATCH MBEGIN MEND
      typeset -g
REPLY=${1//(#m)[^a-zA-Z0-9"\/:_.-!'()~"]/%${(l:2::0:)$(([##16]#MATCH))}}
    }

(Please forgive a forced line break before "REPLY".)

Example:

    % pwd
    /home/romka/hello world

    % url-encode $PWD && print -r -- $REPLY
    /home/romka/hello%20world

It's suitable for generating OSC 8 and the like. I don't think I ever
wished zsh had a dedicated escape for URL-encoded $PWD.
