ncurses allows it (for more than 10 years).  It's in use in ncurses's
terminfo for the various modified cursor- and function keys for xterm,
as well as for a few extensions (the useful ones from screen).

That might count as "portable" (ymmv).

Notwithstanding that, I've seen very few examples of its use in termcap.
