what about (untested)
function HttpToString(str)
return substitute(a:str, '%\(\x\x\)',
\ '\=eval(''"\x'' . submatch(1) . ''"'')', 'g')
endfunction

Note the use of pairs of single quotes to represent actual single quotes
in a single-quoted string.
The use of a continuation line assumes 'nocompatible'.
