Legendary Superscript problem

Hi guys!

I checked this link but it didn't satisfy me because it is not a real superscript.

This superscript thing makes no sense!

I know that Calibri supports all 0-9 in superscript;
I know that I am able to paste it from clipboard to stupid RichTextBox created by VB6;
and there is no problem (e.g I tried superscript 8);
but I can't do it with code?!?!
Do you think it makes sense after all?

Anyway, is there anyway to use superscripts with API or call from native font or anything?

Thanks a lot!
