Why?

1.19 adds a previews-chat in the server properties, where messages may be formatted and presented back to a user before they finish and send the message. A player may want to know what their message will look like when it's broadcast to discord, especially as Minecraft and discord have different text formatting rules.

What and How?

If previews-chat is enabled, when an unfinished player message is sent to the server, it is serialized using the experimental ToMinecraft serializer. So if a player types **Hello** *World* in Minecraft, a &lHello&r &oWorld&r preview is sent back so they can see what it will look like on Discord.

If the server has the ToDiscord serializer enabled, that should also be used on the preview first, so a message formatted like **Hello** &oWorld&r can correctly be previewed to the player as &lHello&r &oWorld&r

Are there alternatives?

Not that I can think of.

Anything else

No response

Chat preview is used for displaying how a message will be shown in Minecraft, not how it'll be shown in Discord. DiscordSRV doesn't effect how chat messages sent in Minecraft are displayed in Minecraft at all, even if the reserializer option(s) are enabled.
