UTF-8 = Unicode Transformation Format, 8 bit. The transformation
methodology is independent of the character set it represents. The
CANONICAL APPLICATION of this transformation format is to represent
Unicode characters, but it can be considered to be a variable-length
integer representation scheme. There's nothing wrong with discussing
the manipulation of data encoded in this format without having to drag
in the concept of a character set.
