That's fair enough, but the question is should they be taken as equivalent for string-comparison purposes? (English has plenty of cases where different letter combinations sound alike, but we don't consider them equal because of that. That may not be a good analogy though. Also, if there are cases in other locales where strcoll considers non-identical strings equal, the reasoning for it might be quite different.) regards, tom lane
