Sorry, this is all wrong, as I forgot that some characters can not be
put into windows. I find this case problematic, as a series of BMP Han
characters must be encoded in Unicode mode to get 2 bytes per character,
but the private-use characters must be encoded in UTF-16.
Some tests with the optimal SCSU encoder I'm working on gets results
between 26-28 bytes for 10 randomly chosen characters in the Unicode
mode tag range.
