I would think this was correct, as well.

Non-type template arguments can only be constant integers or (maybe in this case) multi-byte characters. A four-byte character value might be the standard limit here. (To be honest, I haven't really worked with Unicode or anything else beyond one-byte characters. Someone else may have a better answer for you.)
