Oh, "burned-in" to your brain, yes I see.
Me as well, though we're probably a minority on this group ;)

Not too concerned about what other terminals don't support,
as long as we do, and document it.
I guess we can make our own extensions too, though would
have to be careful with that.
Setting font faces would be nice.. IIRC there was a Vt100
sequences for 'double wide text' that could somehow be
'extended' to at support FLTK font numbers.
Other terminals certainly take liberties with how we implement
certain features, as long as it's done respecting existing specs.

Yes, me as well.. in DOS days, whatever ANSI.SYS supported was
of primary importance, and I think my \e[0m habit started there.
Doing a quick test, looks like gnome-terminal supports "12m"
but xterm and konsole don't. So indeed, not well supported,
as the wikipedia page warns.
Can't test my linux console; for some reason bold and unbold
look the same on this monitor.. too lazy to noodle in my
monitor's digital menu. I sure miss knobs.
