:-) Yes, but in Windows there are only 256...

This does not work in R 2.4.1 for Windows. 0x2110L returns
an error, and intToUtf8 returns an error on anything except
the simplest calls:
intToUtf8(33) # error. Argument x must be an integer vector
intToUtf8(33:35) # ok
intToUtf8(40 + 0:9) # error. Argument x must be an integer vector
