Answer 1

There's no Superscript comma in Unicode.

However there are :

• Superscript plus sign (U+207A): ⁺
• Superscript minus sign (U+207B): ⁻
• Superscript equals sign (U+207C): ⁼
• Superscript left parenthesis (U+207D): ⁽
• Superscript right parenthesis (U+207E): ⁾

Maybe you can use some other glyph, like the "dot operator" (U+22C5) to simulate a superscript comma: ¹⋅³².

You can also, of course, use NSAttributedString with a smaller font-size and an up-shifted baseline offset to simulate superscripting. However NSBaselineOffsetAttributeName is only available starting with iOS 7.
