The letter Q only has one

[GamerInGeorgia]

The hyphen (‐) is a punctuation mark used to join words and to separate syllables of a single word. The use of hyphens is called hyphenation.[1] The hyphen should not be confused with dashes (‒, –, —, ―), which are longer and have different uses, or with the minus sign (−), which is also longer in some contexts.

@SMBXFan - Okay. Maybe we don't need a U to follow our Q here. But due to "Q-Nova"'s hyphenation, it should be like this: Q-
Nova, and it's being used for line-wrapping, OR Q is a prefix that means something, OR the hyphen is being used to create a compound modifier (so Q must still mean something). Even if you want to argue that Q is sometimes used for personal names, then here:

Some married couples compose a new surname (sometimes referred to as a double-barreled name) for their new family by combining their two surnames with a hyphen. Jane Doe and John Smith might become Jane and John Smith-Doe, or Doe-Smith, for instance. In some countries only the woman hyphenates her birth surname, appending her husband's surname.

So then Q-Nova is the surname combining the last names Q and Nova.
But, you could argue using this excerpt:

Connecting hyphens are used in a large number of miscellaneous compounds, other than modifiers, such as in lily-of-the-valley, cock-a-hoop, clever-clever, tittle-tattle and orang-utan. Use is often dictated by convention rather than fixed rules, and hyphenation styles may vary between authors; for example, orang-utan is also written as orangutan or orang utan, and lily-of-the-valley may or may not be hyphenated.

As for answering to that, I'd be stumped. But maybe now I can write Q-Nova as Q Nova or QNova.
