Yes.

For suitably small values of "correctly", sure. Textual sort ordering
would be by byte values, which might be a bit unintuitive for Unicode
characters. And I don't think upper()/lower() would work very nicely
for characters outside the basic ASCII set. But AFAIR those are the
only gotchas. People in the Far East, who tend not to care about either
of those points, use 'C' locale with various multibyte character sets
all the time.
