Good catch, the `toJavaString` version also looks broken, since it looks for the first 0 byte, but that might just be the high-order byte of a character, which just happens to be 0, for wider char sets (for some reason I had assumed this was okay when thinking about it before).

Though we use Charset to do the encoding, it's probably not a bad idea to test a couple different strings as well.
