Let me be clear. You currently cannot constrain for number of characters in a unicode string. From a business perspective it's unhelpful to think of constraining in that way. By all means constrain on bytes, and if that's close enough for you, use that as a proxy. Or provision lots of space, and count characters in the UI.
