Is there a symbol for potential equality? Essentially I'd like to condense:

$$ (a = b) \lor (a \ne b) $$

so that I can express the phrase "a may or may not be equal to b". Apologies if my syntax is not entirely correct; I come from a computer science background.

The most common usage I have seen is

$$a \overset{?}{=} b$$

Usually its context I've seen is before you're trying to prove that they indeed equal or something of that matter.

The Unicode symbol ≟ can be used for questionable equality.
