In one word: don't.

Since PyQt has to respect the constraints of Qt (C++), what do you 
expect? After rewriting uic and qt designer, there's even more trouble 
ahead of your road (qt meta system, translation, ...) 

I have a hard time to find the upsides from this move in python3.
What would you think about some wonderful python open source 
application, that is written with all kind of _labels_ in hanzi, kanji 
or hanja? I guess, it would prevent you from modifying anything in that 
code. Similar, a lot of people in the world are lost with cyrillic 
labels. 

Imagine, Phil would write his code in some gaelic language? Even if  
(mostly) ascii based, only a small population would be able to 
understand the code. To get this straight: even written with proper 
english labels, comments and docuemtation, it's hard to grok 
completely. Try it.

Unicode labels are a silly form of obfuscation to me. 
If you like that, why don't you start hacking in APL, then?
