This is a feature. It is not a feature which I agree with (far from 
it:-), but a feature nonetheless.

CFStringCreateWithCharacters expects a unicode string. The Python 
format specifier for unicode strings accepts "normal" strings, and 
interpretes them as a binary data stream containing UTF16 unicode data.

CFStringCreateWithCString() does what you want, as does the simpler 
toCF(), which will
convert most Python datatypes to the equivalent CF representation.
