Well, it is not so good. Please read my next message to Luis.

IMHO It is perfectly acceptable to declare you don't interpret those
symbols. After all they are called *compatibility* code points. I
tried "a quater" symbol: Google and MSN don't interpret it. Yahoo
doesn't support it at all.
NFKD form is also more tricky to use. It loses semantic of characters,
for example if you have character "digit two" followed by "superscript
digit two"; they look like 2 power 2, but NFKD will convert them into
22 (twenty two), which is wrong. So if you want to use NFKD for search
your will have to preprocess your data, for example inserting space
between the twos.
