That shouldn't matter. He was matching the same hex escape he used in
his string (viz., \xa3). It shouldn't matter whether it's unicode or
just random data; the match should go through (or fail) in either case.

Not really, because I don't understand Oniguruma (the regexp engine);
I'm barely smart enough to _use_ regexps. ;) But seemingly, you can't
use hex escapes in character classes, so you have to use the literal or
do other things to work around it (see last two posts above).
