I see many comments about Han unification being a bad idea but I am not seeing any reason why it was such a bad idea. I am from a CJK country and I find it makes a lot of sense. Most commonly used characters should be considered identical regardless of whether it is used in Chinese Japanese Korean or Vietnamese. Sure there are some characters that are rendered improperly depending on your font but I don't think that makes Han unification a fundamentally bad idea.
Is it really depending on the font, or is it depending on some language metadata? Having it depend on the font seems stupid, since a font ideally be able to represent a languages which use a script encodable using Unicode.
