Greater-than with question mark above

It turns “is greater than” into “is it greater than?” The plain sign > states a fact: a > b. Putting a question mark over a relation sign is an established way to show that the relation is the thing to be tested. The best-known example is ≟, “questioned equal to”, written when you set out to check whether two sides match. ⩼ does the same for greater-than, and its mirror ⩻ does it for less-than. Unicode gives no formal definition beyond its name, so in a given text the author's own explanation decides the details.

It was encoded in Unicode 3.2 with hundreds of other mathematical operators gathered from the character sets used by mathematical publishing and markup. Its entity name, gtquest, comes from ISOAMSR, the standard list of named relation symbols that MathML and HTML also adopted. Not every font draws it; if yours does not, you may see an empty box instead.
