Thanks Gabriel, I hadn't thought about the str() function that way - I
had initially used it to coerce the attributes which are type int to
type str so that I could write them to the output file. I've rewritten
the buildString() function now so that the unicode objects don't get
fed to str(), and apparently windows copes ok with that. I'm still
puzzled as to why python at my end had no problem with it...
