Wow, this works perfectly fine. However, I still have a problem with binary
file representation in a text field. Zeros (00h) are not visible at all
(zeros are not represented by white space as expected). So for example:
this:
"2E 64 6C 6C 00 4F 4C 45" (in hex)
should be represented as:
".dll OLE"
but is represented as:
".dllOLE"

Maybe its because of chosen encoding but "mbcs" was only one which could
displayed binary file in QTextEdit at all:
s = codecs.open(self.filename,'rb','mbcs').read()
self.ui.textEditAscii1.setPlainText(s)

Do you know any other encoding for binary files which could be used and
handled correctly by QTextEdit or should I change my approach completely and
try to display binary files other way?
