[scribus] python, upper() and international characters

[Ladislav DANKO]

Hi folks,

may I have a question? I'm playing with Python in Scribus and I need to
do upper() on international string, for example "kotrbová" (note acute
above last character). When I do it the result is "KOTRBOVá" -stil the
last character is small.

Can anyone point me to the right place in documentation when I can find
the problem described and in ideal situation are there some examples?

Thanks in advance,
