Well, of course, a terminal emulator can load any font, even
proportional, but as it places them in the grid, it will look ugly as
hell (like this one: https://askubuntu.com/q/781327/398785 ).

So, if someone is running a mixture of applications requiring implicit
vs. explicit modes, they'll have to continuously toggle the

I'd like to propose encoding italics and similar display attributes in
plain text using the following stateful mechanism:
• Italics on: ESC [3m
• Italics off: ESC [23m
• Bold on: ESC [1m
• Bold off: ESC [22m
• Underline on: ESC [4m
• Underline off: ESC [24m

Hi guys,
Having been a terminal emulator developer for some years now, I have
to say – perhaps surprisingly – that I don't fancy the idea of reusing
escape sequences of the terminal world.
(Mind you, I don't find it a good idea to add italic and whatnot
formatting support to Unicode at all...
