Right. Hashed passwords is one example of when internationalized
comparisons wouldn't work. I'm sorry if this wasn't clear in my earlier
note.
However there is a risk that normalization _introduce_ differences: if
two systems use different normalization algorithms that leads to
different outputs for the same input, the hashes won't match either.
