If you're willing to settle for merely not having to implement ISO 2022
yourself, rather than erasing it completely, have you tried luit?


Hmm, one issue with luit is that it doesn't interpret Save Cursor and Restore Cursor (ESC 7 and ESC 8), which are supposed to save and restore the character set shift state.

So adding luit to a "UTF-8 vt220 emulator" is not quite enough to look good in vttest.

In practice I would guess few applications rely on this (I hope).
