First, you need to find out what the respective types are: print type(self.title), type(self.content), repr(self.title), repr(self.content) With that information, as a very important next step, you need to understand why the error occurs. Then, you need to fix it, e.g. by converting all strings to byte strings. Suppose title is a unicode string, and further suppose the output is to be encoded in cp1252, then you change the line to rc_file.write(u"\n\n".join([self.title.encode("cp1252"), "### BEGIN CONTENT ###", self.content])) Regards, Martin -- http://mail.python.org/mailman/listinfo/python-list
