What if a player with a German locale used their favorite anime character’s name? How do you know whether to use Chinese or Japanese characters on somebody else’s PC? Even a Chinese player should see Japanese characters there. But you would first of all basically need to ask the German player with a drop down menu which language their name is in, which will never happen, so we just assume Chinese. It’s just broken.

I think we clearly need an in-band solution. Some character that switches the Asian glyph variant, or separate characters altogether. The former would be annoying for non-variable sized Unicode because you’d lose the ability to use random access into a large corpus of text, because you’d need to scan the entire text to find out the current Asian glyph variant mode.. sigh
