Why? I can't imagine any use-case where you're dealing with enough
data outside the BMP to make using this instead of UTF-16 a real win.
You have a case where you're dealing with a large amount of Egyptian
Hieroglyphics or obscure Chinese characters, and it's worth adding the
complexity to go from four bytes to three in some cases, but not use
SCSU or a standard compression like zlib's?
