Maybe it makes sense to look at the character categories.

Clearly the operators cannot include identifier characters. And the latter can consist, as far as I understand, from categories L (letter), M (mark), N (number), Pc (punctuation connector). Now the operators cannot include categories C (other) and Z (separator) since they are not printable. The remaining characters can be used to form the operators.
