Is it

kdialog will accept a limited form of markup as text, including xml
character escapes. so you should be able to display polish text
correctly using this method:

>>> import os
>>> s = """Wszyscy ludzie rodz\xc4\x85 si\xc4\x99
...  wolni i r\xc3\xb3wni pod wzgl\xc4\x99dem
...  swej godno\xc5\x9bci i swych praw. S\xc4\x85
...  oni obdarzeni rozumem i sumieniem i powinni
...  post\xc4\x99powa\xc4\x87 wobec innych w duchu
...  braterstwa."""
>>> s = s.decode('utf-8').encode('ascii','xmlcharrefreplace')
>>> k = os.popen('kdialog --inputbox "<p>%s</p>"' % s)
