Are you referring to "US International with AltGr dead keys"? I use it too for programming, English text and sporadic Italian text -- so I'm not annoyed by the dead keys unless I actively look for them.

FWIW, growing up in Italy I have the same complaint as the OP about not being able to type È in the italian keyboard -- it comes up somewhat often in prose.

My only complaint is that I occasionally write to colleagues named Paweł or Michał which are not typable

That's funny, the swedish keyboard can handle éèÉÈúùóò and so on, with deadkeys but we don't need much of them. Also üîñ on top of the native ÅÄÖ. The keyboard has five deadkeys concentrated on two buttons with shift and altgr alternatives. The only special keys we realy need is åäö and é. Very seldom à or á, forget which one. And then usually it's a borrowed word from french or italian.

Currencies also: €£$

The annoying part as a programmer is the way to get to {[]} with altgr button and right pinkie finger, that takes dexterity... Oh, and <> that are bottom left beside z on the same button with shift.

I always get a bit confused by those namings - maybe? On the one I'm talking about I'm realizing now it's actually two presses rather than one for É (E -> altgr+').

Other commentor mentioned EURKEY, which has it but is otherwise quite similar
