Hmm in that case, we'd have to call it "ucs2" or "ucs4" depending
on how Python was compiled ;-)

I'm not bound to "unicode" at all, just don't think using "string"
for text data will really make people think twice often enough
and then you end up having binary data in a "string" again -
with the only difference that it's now using the Unicode type
My personal favorite is "text" for text data.
