There's no standard heuristic for doing this. Windows has one built in called MLang that IE uses, but I don't think the heuristic itself is published. Encoding detection also happens to be the source of many humorous "bugs" in Notepad: http://blogs.msdn.com/b/michkap/archive/2006/06/14/631016.aspx > I've found this: > http://www.macosxguru.net/article.php?story=20030808081801868 but it seems > ridiculously complex... That is pretty poorly engineered code: an explosion of classes for no good reason. If I were to write an encoding detector, it would probably be a much simpler big if block. --Kyle Sluder _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
