“Utext: Rich Unicode Documents § HTML Utext”, Gwern2023-10-08 ()⁠:

An esoteric document proposal: abuse Unicode to create the fanciest possible ‘plain text’ documents.

How can we make Utext useful for websites?

By adding in the single missing ingredient of hypertext: active, clickable links.

And we can do that by defining a HTML wrapper which permits only literal text displays (in <pre> tags), <a> HTML hyperlinks, and the minimal amount of CSS to render this pleasingly on desktop/mobile.

This HTML Utext gives us a highly-esoteric textfiles-style format which nevertheless could work for a website.
