hi.

is there a smarter way to do percent decoding (and encoding) other than
a mere succession of sed substitutions?

What do you mean "percent decoding (and encoding)"? You want to convert
ratios to percentages? Values not allowed in URLs to ASCII hex codes?
printf format strings to output?

I don't remember which characters need to be encoded, but for
illustration here is a version which encodes all but letters and
whitespace.

perl -wple 's/([^\w\s])/sprintf("%%%02X", ord($1))/eg'

man perlop and man perlfunc describes s//eg and sprintf.
