Excellent to see, the ESC ambiguity problem is one that has especially bugged me. I hope there's a plan to standardize this with the relevant organizations! I

Excellent to see, the ESC ambiguity problem is one that has especially bugged me. I hope there's a plan to standardize this with the relevant organizations! I worry that's the only way to see widespread adoption.

Yes, I can imagine a mostly-backwards-compatible, but much improved, standard; let's call it VT-2021.

  If you are native English speaker, then start with kind of "caniuse" site, but for terminals and VT, please. It will help a lot if we will be just aware of available features in existing terminals and their compatibility with standards.

    Not a web site, but terninfo and termcap databases, normally present on a Unix system, have this information. I would hazard to say that some basic subset of VT100 commands is "universally" supported, even on Windows if one uses Windows Terminal. Various obscure high-end features from 1980s, like programmable font bitmaps, or sixel support, much less so. Also, modern terminals support Unicode, including emoji (as double-width symbols), which was unimaginable in 1980s or 1990s.

      How to display terminfo in a consumable way? What about non-standard features, like drawing, sixels, sound, mouse, touches, clipboard, fonts, true color, transparent background, color emoji, double size text, etc.?

      And yet, I feel like that database doesn't succeed in replacing a website that tells me "the following terminals support OSC 8 and with what awkward limitations", which is knowledge I find both useful and important for web browsers despite being able to do runtime tests to determine the support of most features. "Oh, it turns out 78% of my users wouldn't be able to parse OSC 8 even if I went to the trouble of using it... maybe I'll work on a different feature today".
