These are important points that need to be emphasized. Those who would
devise various "improvements" to UTF-8, etc. often fail to realize how
much careful thought went into their design. You can jump into the
middle of a UTF-8 string, and you'll need to move fewer than a code
point's worth of bytes to resynchronize with the reference frame, for
example. UTF-8 is also very robust with respect to data corruption.
