Ouch. I wouldn't have thought that.

Adding another library to the list of dependencies might be overkill to 
get that kind of problem solved, but when the JDK didn't offer me the 
kind of Unicode processing that I wanted, I found ICU to fill my needs.

It is on http://site.icu-project.org/ and knows more about Unicode than 
you ever wanted to know.
Including stuff like: "The rules for converting between upper and lower 
case depend on the locale, so which one do you want?"

On the other hand, if it's just filenames, you probably want to be 
bug-for-bug compatible with what the file system does. In other words, 
use just file system functions to find out what name the file ended up 
being, or whether there's a name collision.
