10 u:'♥♦♣♠' ♥♦♣♠#10 u:'♥♦♣♠' 12
I can't make heads nor tails of this result. nuvoc suggests that 10 u: should be used to generate unicode4 (which probably means that it would use the ucs-4 encoding, containing a utf-32 representation of the argument characters), but while it's literally the case that the result is in J's unicode4 format: datatype 10 u:'♥♦♣♠' unicode4 ... it does not look like the argument characters were encoded in this format. -- Raul ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
