Is there an Unicode Symbol for Superscript comma?

Question

Answer 1

I had 40,000 for an exponent and was looking for a superscript comma. The best I could find was a Calibri U+031B, a combining horn, so I was able to make a reasonable looking exponent: one chance in 10⁴⁰̛ ⁰⁰⁰ of life originating by natural means. When I was using it in combination with Times New Roman, I had to add a extra space after the combining horn, but here I had to delete that extra space. After posting, it looks like that effect is defeated.
