well, I thought unichr() was a built-in Python function...

you didn't answer my question: is there any reason why
unichr(0xXXXXXXXX) shouldn't return exactly the same
thing as "\UXXXXXXXX" ?
in 2.0 and 2.1, it doesn't. in 2.2, it does.

really? according to the documentation, it creates unicode
*characters*. so does \U, according to the documentation.
imo, it makes more sense to let "characters" mean code points
than code units, but that's me. the important thing here is to
figure out if \U and unichr are the same thing, and fix the code
and the documentation to do/say what we mean.
