EDIT: Remove argument about ease of development, because refterm is easy.
This bugs me every time. "Wow, this software works so good, but we are not gonna make our software like that, no, we'll stick to our shite implementation."
Its' description says also: "Reference monospace terminal renderer". "monospace" is there for a reason.
It's worth mentioning though, that Windows Terminal also defaults to Cascadia Code and Cascadia Code was installed automatically on my machine, so it's de-facto the new monospace standard font on Windows starting from 10.
cascadia is as borken as the other font, so what now?

maybe writing a unicode rendering isn't that easy? maybe drop the attitude?
You came here with an attitude.

Nobody said he made a fully functional better terminal, just that the terminal rendering was better and functional. Doing everything needed for a fully functional terminal is a lot of work, but doing everything needed for terminal rendering isn't all that much work.

easily falsifiable bullshit found to be false.
If you were to open refterm once, you'd see a text that explicitly states "DO NOT USE IT AS A TERMNIAL EMULATOR", or something like that (can't open it now to copy exact).
That seems like it would be unaffected by correcting font rendering.
It is.
"... extremely slow Unicode parsing with Uniscribe and extremely slow glyph generation with DirectWrite..."
Glyph generation is about rasterising text, because you can't just feed it the font file.
This is an edge case as much as building a rasterizer directly into the terminal is an "edge case".
The fact that a random commenter on HN used a non-monospaced font with refterm actually makes it a use case.
I do, however, agree that it is an edge case with a very low probability.
The Microsoft terminal doesn't render monospaced fonts, the overwhelmingly common case, nearly as fast as refterm. If rendering variable-width fonts is somehow intrinsically insanely expensive for some reason (which I haven't seen anyone provide good evidence for), then a good implementation would still just take refterm's fast monospaced rendering implementation and use it for monospaced fonts, and a slower implementation for variable-width fonts.
That is - refterm's non-existent variable-width font rendering capabilities do not excuse the Windows terminal's abysmal fixed-width font rendering capabilities.
Also, it's worth noting that this isn't a compelling argument in the first place because the windows terminal doesn't even come close to rendering readable Arabic, it fucks up emoji rendering, etc – all cases that Casey was able to basically solve after two weekends of working on this.
Windows Terminal, for some reason, gives users the option to change their font to one that isn't monospaced, so I'd argue that it should render them correctly if the user chooses to do that.
Casey threw something together in a matter of days that had 150% of the features of the Windows Terminal renderer, but none of the bug fixing that goes into shipping a production piece of software.
That screenshot you keep parading around is a small issue with a quick fix. It's not like Casey's approach is inherently unable to deal with punctuation!
You don't discard the entire content of a scientific journal paper because of a typo.
"Sorry Mr Darwin, I'm sure you believe that your theory is very interesting, but you see here on page 34? You wrote 'punctuted'. I think you meant 'punctuated'. Submission rejected!"
> The "complaining developer" produced a proof of concept in just two weekends that notably had more features[1] and was more correct than the Windows Terminal!
But now apparently pointing out that "MS was right not to want to take shortcut in unicode rendering" morphed into "criticizing in bad faith refterm for not being production ready"
Who's not arguing in good faith here?
Considering Casey himself puts front and center the disclaimer that this is solely intended to be a reference and goes into as much detail in his videos I don't know where you got this from. I don't think anyone is under the illusion that this is could replace the actual terminal. It's just meant to show that there's a minimum level of performance to be expected for not a huge amount of effort (a couple weekend's worth) and there is no excuse for less.
Who said that? Refterm isn't a fully functional terminal, it is just a terminal renderer bundled with a toy terminal.
absolutely standard
