[PyQt] QScintilla 2.4 doesn't complete correctly with umlauts

[Hans-Peter Jansen]

Hi Phil,

The python bindings of QScintilla 2.4, as used in Eric 4.3.4, does not 
complete correctly, if the words contains umlauts (the words in question 
get truncated just before them). 

I might remember this as a longer standing problem, but didn't got around 
reporting it until now :-(.

As I have a use case for this ATM, I'm highly interested in a fix/patch.

Thanks,
Pete
