If you need to sort strings, or do anything more complicated than storing strings, you'd better decode the strings and not keep them as UTF-8. > The magic is called array.

Unless you are so OO-maniac as to consider that a 10-elements structure should be an extension of a 9-elements structure... -- J-P.
