The hole in a character

Forgive any naivety. I have come from SO to SE to ask a question.

I am looking for a font, where the hole in a character ie O, A, P, Q. Can be used to insert an image. I do not need a recommendation for a font. But what I am asking for is the word used to explain this area. Can someone please provide me with the specific word that explains the whitespace within these particular letters.

In typography, anything that isn't ink is referred to as whitespace. An area of whitespace that is either partially or entirely enclosed by a letter, whether uppercase or lowercase, is typically called a counter. However, there is an exception to this: in the lowercase letter "e," the whitespace is also referred to as an "eye" (as per its usual shape).

The enclosed or partially enclosed whitespace in a character is usually called a counter. Examples of characters with a counter include C, e, S and H. The round or curved enclosed portion of letters like D, g, p and o can also be called a bowl.
