‽

‽ is a punctuation mark known as the interrobang. It is used for sentences that are both exclamations and questions at the same time. For instance: In surprise Bob yelled, "can he actually do that‽" Since there is only one piece of punctuation at the end of the sentence where we can put either the binary of conditions of is/isn't exclaiming and is/isn't questing then we have to put up with these messes of hybrid punctuation.

But why not take it further? Sometimes it is useful to emphasise that only one clause of a sentence is a question. The time that this comes up most is from character dialogue where the standard way to punctuate it seems to be as it is in the following sentence. "How many pencils are in that pot?" the old man inquired. This isn't particularly satisfying because it looks like it is two sentences (which would require us to use a capital letter on the T of the). Compare it to the sentence: "There are three pencils in that pot," the young man responded. Notice with the comma it is clearly one sentence.

What we need is something which has the length of pause of a comma, but the toggled state of being a question. I give you a solution:

You may have any length of pause along with being a question, being an exclamation, neither or (*sigh, xor) both. Most of these symbols are not properly recognised, but the beauty of the system is that you can work out their meanings. It is logical and complete.

What I'm less sure on is how you could represent something which is mostly a question but is also slightly exclamationy, or the other way around. There are potential for any binary fraction of them such as:

A bit dodgy

But you get into issues of order and of having more dots in your ellipsis which implies a longer pause. I'm not sure it is workable.
