I think this is one place where the docs should have a clarification added
"For character with an ordinal value < 256"
I say that because pack is mainly used for packing structures to pass to C
routines. Those routines may not like it very much if the chr(202) is encoded
as utf8.
IMO, "U" should be used for pack/unpacking utf8 characters and "C" should continue
to pack the value & 255
