@mayank @luna yes and no, what formatting (in the form of html tags iirc, been a couple of years since ive had my hands in the guts of this) is allowed is controlled by the server, and vanilla mastodon scrubs most of it (or at least used to, idk recently) as an intentional choice by the designers. but even so these are html tags that are then sent to the frontend, which decides how to render those html tags. note how some frontends change the color of monospace, others don't, for instance.
