Hello,
Using this mod in the Prominence modpack ( https://modrinth.com/modpack/prominence-2-fabric ), some items will have the § symbol in their name. Trying to share an item in chat with this symbol, will result in a server kick with the 'Illegal characters in chat' message.

Using ShowMeWhatYouGot-1.20-1.1.1

Having the same issue in the Fantasy MC modpack. Most likely related to the color code characters from Tierify

I have the same issue and can confirm it's due to Tierify.

Anyone has found a fix ?
