236# way is %XX-escaped utf-8 encoding.
237# Naturally, Unicode strings have to be converted to their utf-8 byte
238# representation. (No action is required on 5.6.)
239# Byte strings were traditionally used directly as a sequence of octets.
240# This worked if they actually represented binary data (i.e. in CGI::Compress).
241# This also worked if these byte strings were actually utf-8 encoded; e.g.,
242# when the source file used utf-8 without the apropriate "use utf8;".
243# This fails if the byte string is actually a Latin 1 encoded string, but it
244# was always so and cannot be fixed without breaking the binary data case.
