Would you mind telling us (a) what that encoding is (b) how you came
to that knowledge (c) why you just didn't do
test = os.popen('kdialog --inputbox %s'
%(data.encode('that_encoding')))
instead of
test = os.popen('kdialog --inputbox %s' %(data.encode('utf-8')))

It wasn't being passed to kdialog; there was an attempt which failed.

And the font you *were* using is what? And the font you are now using
is what? What facilities do you have to use different fonts?

The essential difference is that setting a default encoding is a daft
idea.

Before I retract that back to one contender, I'll give it one more
shot:
1. Your data: you say it is Polish text, and is utf-8. This implies
that it is in Unicode, encoded as utf-8. What evidence do you have?
Have you been able to display it anywhere so that it "looks good"?
If it's not confidential, can you show us a dump of the first say 100
bytes of text, in an unambiguous form, like this:
print repr(open('polish.text', 'rb').read(100))
2. Your script: You say "I then manipulate the data to break it down
into text snippets" - uh-huh ... *what* manipulations? Care to tell
us? Care to show us the code?
3. kdialog: I know nothing of KDE and its toolkit. I would expect
either (a) it should take utf-8 and be able to display *any* of the
first 64K (nominal) Unicode characters, given a Unicode font or (b)
you can encode your data in a legacy charset, *AND* tell it what that
charset is, and have a corresponding font or (c) you have both
options. Which is correct, and what are the details of how you can
tell kdialog what to do -- configuration? command-line arguments?
HTHYTHYS,
