Support more xterm/VT100 control characters

[colindean]

Problem

I use some VT100 control characters in my scripts. I've found that Elementary Terminal seems to ignore them.

bigtext:

#!/bin/sh
text="${*}"
printf "\033#3%s\n" "${text}"
printf "\033#4%s\n" "${text}"
printf "\033#5"

$ bigtext this should be big
this should be big
this should be big

Proposal

Support xterm/VT100 control characters

One document on them:

Prior Art (Optional)

xterm and Apple Terminal support this, but iterm2, gnome-terminal, terminator, and alacritty do not. I only tested those.

We are using libvte for this, the same library used by GNOME Terminal, please open a bug report there: https://gitlab.gnome.org/GNOME/vte

Looks like there was discussion about this 2+ years ago: https://gitlab.gnome.org/GNOME/vte/-/issues/195

The state was that there wasn't adequate demand to devote resources to implementing it:

So, there are two levels to this story:

• Is there demand for double sized letters to make it worth it?
• Do we already have an even remotely usable standard for that?

In my firm opinion, the answer is "no" to both of these questions.

Looks like this isn't likely to happen anytime soon.
