Yeah... Because all characters are UTF-8 more often than not nowadays, your point?
The point is, we already can use unicode characters on Discord (both tags and usernames) so why not Minecraft as well? If we wanna be consistent on how we moderate this server, then we would have to ban all users on Discord that have a tag/nickname that contains at least one character that isn't A-Z, 0-9, and an underscore.
*Sigh*... Because people can use &k to iterate through thousands of Chinese characters per second and tank the framerate...
