This looks a but messed up.  The bytes that make up a multi-byte
encoding like UTF-8 have no meaning at all except as numbers (well, bit
patters as much numbers but it the same thing for most languages).  Of
all the operations you decide to permit on this 8-bit character type,
only the conversions to and from integers are useful for individual
UTF-8 bytes, and they are needed every time for every use of the byte!

A character type should represent characters, with some set of relevant
operations depending on the design, and UTF-8 sequences should be
represented as byte sequences with numeric values.
