Is that sequence you describe impossible to do? Many languages have
more the one character considered as one letter of their alphabet.
Spanish used to, or still does in traditional mode, with "ll", "ch"
and many other languages do too, like many African languages with
"gb", "nk" and the likes.Of course they can all be formed with a
zero-width-joiner U+200D, you just need an IME to do it. If inverted
interrobang is included, why can't those be?

Don't we all have to convince font designers to include our glyphs?
"Unicode encodes characters, not glyphs."
