The FAQ explains half of it, except that in your case, substitute what
it says about "terminal" with "file object". Python plays it safe and
does not implicitly encode a unicode string when writing into a file. If
you have a unicode string and you want to .write() that unicode string
to a file, you need to .encode() the string first, so:
string_with_unicode = u"Realtors\xc2\xae"
otherwise, you can use the codecs module to wrap the file object:
f = codecs.open('filename.txt', 'w', encoding="utf-8")
f.write(string_with_unicode) # now you can send unicode string to f
