(You have something odd in your emails -- it seems like leading spaces
are transformed into char 240.)
I've now changed this to recognise some hex numbers if they're preceded
by #x or 0x. Just looking for "bare" hex numbers may return too many
false positives.

That wouldn't help much since the string has to be transformed to a
number in the right base.
