Trying to make StringIO handle unicode and pass it through to

FieldStorage to eliminate the error:

self = FieldStorage(None, None, ''), line = '{ "data": "Joe Doe 1" }'
    def __write(self, line):
        """line is always bytes, not string"""
        if self.__file is not None:
            if self.__file.tell() + len(line) > 1000:
                self.file = self.make_file()
                data = self.__file.getvalue()
                self.file.write(data)
                self.__file = None
        if self._binary_file:
            # keep bytes
            self.file.write(line)
        else:
            # decode to string
>           self.file.write(line.decode(self.encoding, self.errors))
E           AttributeError: 'str' object has no attribute 'decode'
