Sure, but then that's a very loose meaning of "requires" unicode support if all the people who "require" it probably aren't even going to try to use it even if you support it.

Ironically, isn't part of the issue that most "engineered" keyboards in the US don't have any innate way to type those, and thus require your "programmed" OS or application to have the support needed to even type those characters with some chord of keys?
