The issue was related to UnicodeString validator. It seems that tw2 forms expect an unicode string when rendering values while tw1 forms expected an encoded string.
Default behavior of the UnicodeString validator is to convert value to unicode when receiving it from the web (on form submission) and convert it back to a utf-8 encoded string when having to send it back to the browser. While this usually makes sense it breaks TW2. The latest commit on sprox should fix your issue as it tells to the validator to avoid encoding back the string when sending it out, this makes the tw2 field receive an unicode instance and work as expected.
