Note that only the values=[] option is problematic here. If you're using 
a proper vocabulary, you're fine.

Then you're ignoring the obvious solution: a vocabulary (or source). As 
long as you provide a token that's a pure-ASCII representation of the 
value, you're fine. You can use whatever you want for the values (even 
arbitrary objects). All you need is a one-to-one mapping from tokens to 
objects.

To create the vocabulary you can use SimpleVocabulary.fromItems() which 
takes a list of (token, value) pairs.
