Is there an Unicode Symbol for Superscript comma?

Question

While making a translation to a YouTube video (translations can only be in Unicode, no other markup is possible as far as I know of), I stumbled across the concentration of H⁺ in orange juice. It is supposed to be one times ten to the negative 3.5 molar.

I'd like to write it down as "1·10^-3,5 M" (mind the comma, it is translated to dutch). The problem is that I can not find a superscript comma or even a superscript period between all 120,520 unicode graphical characters.

Does someone have an idea on how to solve this?

Answer 1

As far as I know there is no unicode for superscript comma however you can use (U+22C5) as dot seperator.

Answer 2

There exists two, but the first is more useful for your use case.

U+1d112 Musical Symbol Breath Mark

U+02BC Modifier Letter Apostrophe

edit: thanks to Rahul Tripathi, I've looked into a period character. U+22C5 Dot Operator

On most fonts, it looks real weird. But on the font Palatino, it's perfect.
