What is a regular expression for any unicode character that visually resembles a letter o or letter O?

I am not looking for European or non-European letters that sound like a letter O when pronounced aloud.

We are seeking a list of characters with a only a visual resemblance to O (no auditory resemblance).

Here are some examples of characters, but this is not comprehensive.

This is a small sample, it is not all of the characters that look like a letter o or O or a circle
