help wanted regarding displaying Japanese characters in a GUI using QT and python

[prats]

sorry I did not correctly read your point. I works fine. Thanks for
your help.
I have one more query. It was said that the text I was supposed to show
was written using "ISO-2022-JP" charset. But It didn't when I decoded
it using that charset. But it worked fine with the "shift-jis"
encoding. Is it the default charset used by python i.e. I mean to say
bytes would be by default "shift-jis"?
