We changed the parser not to define UNIQ_PREFIX a while ago to prevent XSS attacks, however the language converter still uses that constant which results in E_NOTICE being emitted (it gets cast to "UNIQ_PREFIX" by php) whenever a language (such as zh) that uses the language converter is used, the code in question also probably doesn't do what it's supposed to do now...
It seems this was fixed at some point in the past.
