I think pypinyin should handle different pronounciations ok. Well, at least this sounds promising:
The new word tokenisers should help a bit too. Today we are updating the schema/database for saved items, so they will work with the new code (this will fix your ‘undefined’ in saved items view)… that’s the last thing to do before roling out the update. It won’t be the last Chinese update, I expect there will still be a few things off.
I’ve been told Traditional characters can be mapped to Simplified reliably, and vice versa I guess.
