>=20

I don't think you can reliably use toLower/toUpper (or any static
method) to do case mapping on Windows. NTFS stores a special file named
"$UpCase" which provides the case mapping for that volume. This file can
have arbitrary mappings. (But it usually has something sane.)

The blog is definitely worth reading, Michael Kaplan is somewhat of an
expert in the use of Unicode in practice.
