I never said there was. The string comes from decode, which I believe returns
a Unicode string. AIUI the Python type system preserves that information
until it reaches the codec, which therefore treats it correctly. My use of
the phrase "the python UTF-8 codec can detect that it's got a unicode string"
might have been a poor choice, but I don't think I'm disagreeing with you.
