What’s wrong with my original suggestion of doing the transformation before the text hits the twtxt.txt file? @prologic, I think it would achieve what you are trying to achieve with this content-type thing: if someone writes ¼ on a yarnd instance or any other client that wants to do this, it would get transformed, and other clients simply wouldn’t do the transformation. Every client that supports displaying unicode characters, including Jenny, would then display ¼ as ¼.

So many clients do client-side transformation already, mostly in the form of @-mentions. e.g: If I @falsifian@www.falsifian.org mention you, that gets transformed into the full proper Twtxt mention syntax. We could in theory transform other things too, but I see little value in doing so? 🤔 – Also it’s probably more a “Client” recommendation anyway at that point right?
