Fix the unicode character limit (0 .. 0x10ffff)

For some reason I had limited things to 0xffff, it really should be 0x10ffff.

We don't actually support a full 32-bit unicode model anyway, since we
use the high bits for the control/meta/^X/special bits, but there was no
reason to limit things to 16 bits when we had 28 bits available.  And
the real limit for real Unicode characters is 0x10ffff.

Add a silly example character past the 16-bit range to the UTF8 demo
from the 'emoticons' block.
