Realms doesn't support certain § fonts/colors

I tried naming my sword on my friends realm and it ended up censoring the name the name in question just being "§d§lThe Sword Of Big" so no reason to censor however it still ended up censoring the word for some reason

How to replicate

1)  take a private singleplayer world and name an item using §3,§l,etc.

2) Do the same thing on a realm

2) occasionally, the word would be censored though there is no reason to be censored

 

it doesnt apply to all cases however, only certain times would it actually censor the entire thing

IE:"§d§lThe Sword Of Big"

it always applies to words that use the § character to make colored letters or bold/italic/underlined/jumbled words

The image with the censored words as the final output is the image taken from a realm, while the other is taken from a private singleplayer world
