Custom chat text formatting?

[patey]

is it possible to use a custom font in chat text? My best guess is that it would have to be created as a formatting code but I couldn't find anything about creating my own

I am quite certain that this will require access to client side (meaning it can't be server mod).

 

As to how to do it - FontRenderer can be extended and replaced (located in Minecraft.class) on startup. You could make extension that could e.g grab 1st character in string-to-render, and based on it - would change font. If you look at how text is rendered you should find how fonts are stored and how to use other fonts (e.g some languages/modpacks have different fonts). Can't be more precise (now) without IDE.

You can also change the font server-side by sending a resource pack to the client when they log in, but clients can decline and it can take a while to download.
