Text Formatting Censored On Realms

If text formatting is typed out on Realms, it gets censored, and one of two things happen. Either the text formatting is replaced with ##, or in the case of signs, the text can disappear completely. Text formatting uses § combined with numbers or specific letters to get different effects, for example §l makes the text bold, or §1 makes text blue. This does work as intended on single player worlds, just not on realms
