Can not get in to server called Minecraft Surperior because I can't get the letters o and r in because there is no more room in typing space

Well that's sad for me because I can't get in only two letters. 😭

Invalid! Server names do not need to be typed in exactly the way they need (e.g. Before the 1.2 update I used to play on a server named PigRaidPvP and I typed just PvP as the server name), just the IP and Port
