porting pyqt application to Qt5

[Salvo Tomaselli <tiposchi@tiscali.it>]

Hello,

I am upstream and debian maintainer of "relational".

The last release uses Python2 and Qt4. I am trying to 
switch to Python3 and Qt5.

The software uses some non-ascii symbols such as ᑌ ᑎ.

I have done a full conversion and there is one major 
problem left.

Sometimes the UI will show the unicode symbols, but 
sometimes will show the squares that are shown when a 
symbol is missing.

Since this occurs randomly I suppose that there is some 
race condition somewhere, but I have no idea of what is 
going on really.

I have written on a pyqt mailing list but I didn't get an 
answer.

Have you ever encountered such problem? For me it is quite 
crucial otherwise I will never be able to migrate it to 
Qt5.

This is a wild attempt, I know… Thanks for your help.

Include me in the replies because I am not on this mailing 
list.
