Unicode drives me crazy...

OK, there are people better placed than I to explain
about Unicode. Check out the following article, for
but in short, you need to understand that WMI hands
you back a unicode object -- not a string, a unicode
object. If you want to write that out to a file, you
must write out a string representation of it. And
that string representation must use one of the
standard encodings (or you could invent your own, I
suppose, but why bother?).
One way of doing this would be:
f = codecs.open ("c:/temp/info.txt", "w", encoding="iso-8859-2")
c = wmi.WMI ()
for port in c.Win32_SerialPort ():
f.write ("Caption = %s\n" % port.Caption)
f.write ("DeviceID = %s\n" % port.DeviceID)
You now have a text file -- info.txt -- which holds
string representations of several unicode objects. If
the characters all fall within the common A-Z/1-9
characters, it will appear just the same as an old-fashioned
ascii file. If the original data represented (presumably)
Hungarian characters, there will be some representation of
that, probably using \x sequences.
This file can be read by any other program which knows
that it's an iso-8859-2 encoding of unicode. (Knows, because
you write the program or because you've told the programmer).
Obviously, if this were an XML file, you would put an
encoding tag or whatever it's called (I'm not up on XML).
