I really like the Spanish style of marking questions at the beginning and end, with ¿ . . . ?
First, you might have a really long sentence that is a question, and not realize that it’s a question until you’re half-way through reading it, or all the way, and then you have to start reading it over from the beginning to re-parse it as a question. With the ¿ at the beginning, the reader is advised up front that a question is coming.
Second, and more directly relevant to this OP’s question, is that a question may be only part of a sentence. The ¿ . . . ? punctuation marks unambiguously just what part of the sentence is the question. Example: Now I ask you, ¿what kind of a punctuation style is that?
I wouldn’t mind it at all if we were to adopt the Spanish style of question marks for regular use in English. ¿What would you think of that?
IIRC, I saw a typewriter once that had a slot for a custom character. The type bar had no built-in type face on the end of it, but instead it had a clip-on type face character. That could be removed and another clip-on type face put on. There was a blank key on the keyboard (like the blank tile in Scrabble). I suppose there were various extra characters you could buy to clip on.
