That's not enough fun:
our %ESCMAP = map { chr($_) => sprintf "%%%02X",$_ } 0..255;

Hmm.. this will depend heavily on the number of escapees in the string.
If you're expecting hardly any, then the best algorithm may be different
dealing with running text in non-Latin script, where every char will match.
Every now and then, I get this sneaking feeling that I ought to write a
generalised "pack" that can do this sort of thing. But usually the
feeling passes.
