Wait a second.

There is nothing about Unicode that would prevent you from defining
string equality as byte-level equality.

This strikes me as the wrong way to deal with the complex collation
issues of Unicode.

It seems to me that by default wide-strings compare at the byte-level
(i.e., '=' is a byte level comparison). If you want a normalized
comparison, then you make an explicit function call for that.

This is no different from comparing strings in a case sensitive
vs. case insensitive manner.
