That's basically multiplying N and m, so you could use a dash like N-m:

That's for the torque unit, Newton meter (which could also be an energy unit), normally with a symbol N⋅m that has the centerline dot as you mentioned.

It's definitely a different unit than if you divide, like N/m, which is surface tension:
