Whenever I try to type with signs in a Bedrock Realm and I happen to use colors (§), the sign will either not show any text (similar to other reports) or will make all the text show up on one line with part of it showing up as hashtags.

(In the photo, the color showing up on all lines is just a visual glitch that's been around for months.)

The sign will still place properly in a private world (when I download the realm and try it there)
