Sorry, I don't think I follow: what is "processing for search orders"
to which you allude here?

I'm not talking about localized features, like for "" to match "aa"
in Danish locales. I'm talking about matching strings that are
equivalent under canonical and compatibility decompositions.

As for user sophistication, AFAIR, Microsoft Word finds "" when you
search for "2" by default, so it sounds like Word considers all users
sophisticated enough for that. I think that's a solid enough
precedent to follow.
