This is correct: as much as it's wrong, Han Unification isn't a problem so long you stick to one language to support and remove all conflicting fonts for the other two locales, which are rarely needed anyway in Asia, it just comes back when you try to support multiple CJK languages at the same time. Unicode coverage of each languages are totally fine for 99% of use cases, the Unification problem is just it's reusing the same address space for all CJK languages.

Well, we all know Unicode Han Unification is fine for not just 99 but 99.99% of use cases. It is those 0.01% that we care about.
