Looking for a specific character

[Schonbergian]

I'm wondering if the specific "O with dot below it" character used in the "Number" abbreviation in the titles of scores like this is still around in the digital age:


I swear I've found it in the past, but can't seem to locate it nowadays.

I am aware of the ordinal Nº character; it is not quite what I am looking for.

[OCTO]

U+2116 gives №, yet if there is line or dot is font depending. Some designers use dot next to o.
