No, there isn't.

There are four titlecase letters and 1294 lower case letters in the
UnicodeData.txt I just checked -- not sure what version that is, and
I didn't count the TAG LATIN SMALL LETTER ... entries, which should
not be converted.

Unicode case conversion, done properly, is locale dependent, and
may change the length of a string.

The operation wanted here is, in all likelihood, conversion to
title case rather than upper case.

I have a crude hack which has worked adequately for me, but I really
can't bring myself to put something that awful in this mailing list.
