You can call it MAMA if you like (but that would also be confusing). It still works just like SS2, not at all like ESC, not even close (i.e. not even like the ESC of old equipments, like that Cristian referred to).

Cristian tried to do that (to some extent), and I said no…

I did. It is misnamed there and for Teletext. And yes, I know there were other ESC sequence definitions before ECMA-48, which still were ESC sequences, not ”jumping” to another codepage.

That’s what I said (though I said SMS and cell broadcast 7-bit charsets; GSM (2G) is somewhat outdated, we're (mostly) on 4G and 5G now).
