Because it’s not actually a good idea.

You create text that is basically impossible to search. Like, for instance, do a Ctrl+F on this page and search for “Bold”. You’ll see the example from OP doesn’t get picked up, because it’s not a B, it’s a 𝗕. And it’s not an o, it’s an 𝗼. And so on. Or how about this? Go on Google and copy-paste this word from OP: “s̵t̵r̵o̵k̵e̵”. Now, stroke isn’t a particularly unusual word, but this thread is just about the only result Google returns. Because it’s not stroke. It’s s̵t̵r̵o̵k̵e̵.

It’s also bad for accessibility. A lot of the time screen readers just won’t know what to do with your bold or italic Unicode text.

And of course this only works for characters for which Unicode actually has these variants. Not a problem with the Latin alphabet, but what about Arabic? Cyrillic? Chinese? Devanagari? Hangul? Not gonna work.

These characters are from the Mathematical Alphanumeric Symbols code block. They’re stylized Greek and Latin letters meant chiefly for use in mathematical contexts. The Unicode standard explicitly advises against using them to fake markup for the reasons outlined above and more. A simple markup language is just about always going to be preferable to faking it with Unicode.

Source? Last I checked, the Steam Deck was very much in the minority even when narrowed down to just desktop Linux.

Yeah. xwayland isn’t gonna die ever probably, so there’s no rush.

It is significantly less powerful when compared to LibreOffice, lacking support for many features. It offers less applications than LibreOffice. It is significantly less customizable than LibreOffice. It’s built on bloated web tech. It lacks RTL support.

I am not paranoid about OnlyOffice’s origin. I also do not think it is the best office suite on Linux by a mile.

Nah, a ton of Linux fans seem to shill hard for Apple for some reason.

Oh boy, Davinci? Don’t hold your breath, it’s super picky even with the more mature GPU drivers.

It’s not an unpopular opinion that Apple is the only one that does sleep right. It is an unpopular opinion that this is only possible because they have a complete walled garden and that open platforms are fucked, especially considering it is easy and common to install applications from outside the App Store on macOS. We used to have sleep figured out, that’s what S3 was. But then hardware vendors dropped it. So yes, drivers and hardware vendors are part of the problem. The Steam Deck is an example of an open platform where sleep works fine.
