[PyQt] Unicode errors with PyQt5?

[Chris Pezley]

Hi,

try setting the sip api to use version 2 at the beginning of your program:

import sip
sip.setapi('QDate', 2)
sip.setapi('QDateTime', 2)
sip.setapi('QString', 2)
sip.setapi('QTextStream', 2)
sip.setapi('QTime', 2)
sip.setapi('QUrl', 2)
sip.setapi('QVariant', 2)

This will make Qt give you unicode strings and get rid of QVariants in 
lieu of native python types. Unfortunately the documentation for this is 
a bit lacking 
(http://pyqt.sourceforge.net/Docs/sip4/python_api.html?highlight=setapi), 
so it is hard to find the api options.
