Nobody's said anything about giving up locale-sensitive sorting. The
question is about locale-sensitive equality: does it really make sense
that 'tty' = 'tyty'? Would your answer change in the context
'/dev/tty' = '/dev/tyty'? Are you willing to *not have access* to a
text comparison operator that will make the distinction?
I'm inclined to think that this is more like the occasional need for
accent-insensitive comparisons. It seems generally agreed that you want
something like smash('ab') = smash('áb') rather than making the
strings equal in all contexts.
Of course, not being a native speaker of any of the affected languages,
my opinion shouldn't be taken too seriously ...
