It's still text only. When I hear text only I already assume it supports all you mentioned.
Text is not ASCII only :)
Beyond text only comes voice calls, video calls and screen share, which are paramount for my discord use case. Me and my friends like to game while sharing our screens, so I game in my main monitor and have a matrix of screens on the second. It creates a LAN party feeling and it's important to maintain connection after some moved out of town.
