To put it another way:

1) Yes, it sucks that these representational differences in strings are
exposed to programmers, who will forever be faced with strings that
aren't EQUAL? but have no really useful difference between them.

2) But as Unicode went that way and made it so that these differences
CAN matter in some (not very useful to most people) ways, we need to
expose that difference; hiding it will cause problems.

As Schemers, we're accustomed to not having warts in our programming
environment; but when we're forced to expose other people's
abstractions, we're forced to accept their warts.
