When naming my Minecraft Realm, the realm fails to retain special characters in both the name and description of realm. I'm not sure to what extent is the inability to use special characters, but at the very least Esperanto characters are not working, (ĈĉĜĝĤĥĴĵŜŝŬŭ).
Attached are screenshots showing the issue in effect.
Reactivated my realm now that 1.9 is out, issue is still occurring after being "resolved". "Test ĈĉŜŝĜĝĤĥĴĵŬŭ" was the string that I used in this new example. The server instead changes everything to "?"s.
