Hey there, I was looking for a font that has those "numbers inside circles". After some search I found Unicode for a few, but the ones I'm looking for (the negative circled numbers) stops at 20, while the non-filled one goes all the way to 50. I was wondering is there a font with more? I know for a fact that Japanese publishers use it a lot and even 50+, I find hard to believe they do it by hand... Any help is highly appreciated.

These are the ones:
❶❷❸❹❺❻❼❽❾⓫⓬⓭⓮⓯⓰⓱⓲⓳⓴
Looking for 21+

How about this one?

Oh, yay! Thank you!

There is also one around with numbers 0>9 as you show but the other up to 99 as half circles. So left half circle 1 followed by right half circle 0 makes 10. I'll try to find a link. No guarantee, alas.

The problem is that it breaks all the time, everytime you change something (like bold, italic, or the smooth/strongh/crips/etc, or tracking)it mess it up. So it's quite annoying to use it, I was praying for a better option (like the one suggested by drf), but thanks for your help!

These dingbats are not made for manipulation like you talk about. The horizontal metrics (advance width) prohibit that.

There's got to be at least one Manfred Klein font with circles around numbers, and probably a few.
