Windows 2000 supports surrogates in Unicode text APIs and 32-bit code points
for OpenType fonts.

Subject: Software support for upper planes?

Are there any platforms out there that currently support planes 1 or 2?
Also, are there any font file formats that are aware of upper planes
(i.e.; use more than 16 bits for the character codepoints)?

I ask because it looks like extension B Unihan characters might be
defined soon, and I have an application that could use them....
