Ok, what if that new character set doesn't include a '?' character?

Then it won't even be usable to write any Western European language,
which is so much less likely than not being ASCII-based that it's not
worth thinking about.
Besides, you're missing another point. Trigraphs exist not only for
people who don't have the required characters in their character set,
but also - perhaps more so - for those who don't have them on their
keyboard, and can therefore not type them easily.
