I'd say it doesn't *really* work. Yes, cStringIO insists on getting
byte strings; it won't accept default-conversion converted Unicode
strings. This is a known limitation.

Even when you use StringIO.StringIO, it still will use the pyexpat
reader, which will require byte strings; the Unicode string in the
StringIO object will then get default-converted. So if you have any
non-ASCII characters in your Unicode string, you'll get a Unicode
error with your approach.
