The mod_rewrites encoding can be changed with option
'noescape|NE' (no URI escaping of output)
This flag keeps mod_rewrite from applying the usual URI escaping rules to
the result of a rewrite. Ordinarily, special characters (such as '%', '$',
';', and so on) will be escaped into their hexcode equivalents ('%25',
'%24', and '%3B', respectively); this flag prevents this from being done.
This allows percent symbols to appear in the output, as in
RewriteRule /foo/(.*) /bar?arg=P1\%3d$1 [R,NE]
