Yes. That's exactly what termcap, terminfo, tput, etc., were created
for. You don't emit ANSI. The program uses a device-independent
approach and $TERM is used to find the device-dependent bytes to send,
which may be ANSI sometimes.

As my other email made clear, ls only defaults to ANSI escapes but
defining LS_COLORS means non-ANSI can be used.

Lots. Note how all of these terminal definitions on this Ubuntu system
use a different escape sequence to set the foreground colour to 4.
There are others, this was a random selection after a quick grep.
