But, ,|._2]\'asdf' would give us dfas instead of fdsa, so I do not think that that is a viable option. Ok, you are right though, it's easy to show that J can handle unicode characters larger than 16 bit: 3 &u:inv 20086 乶 # 3 &u:inv 20086 1 The displayed character looks somewhat different than what I expected from http://en.wikibooks.org/wiki/Unicode/Character_reference/20000-20FFF but I do not know enough about the character to say that this is an error. So, ok, they are asking for special treatment of combining characters. I think that that needs better treatment than was given, and will take that up on the rosettacode site.
