    I had to change my implementation of normalization because of this
    (my static tables of canonical decompositions use 16-bit entries for
    BMP blocks), but it was not a big deal.

    I'm more concerned with killing the myth that Unicode is a 16-bit
    encoding than with that minor inconvenience.
