Postgres never considers that two distinct strings are "equal". If the
locale setting considers these equal (which isn't entirely clear from
the given evidence), PG would then sort them on the basis of their
character code values.
A possible workaround if you need to consider them equal is to strip the
accents before sorting (ie, something like "ORDER BY to_ascii(col)") but
this may well throw away more information than you want ...
