The supsc function translates a normal character to a UTF-8
superscript character. The function can be used to
generate superscripts for many common characters. Most alphabetic
and numeric characters have UTF-8 superscripts. This function is useful
because it saves you from having to look up the superscript character
code, or copy and pasting from the internet. If a corresponding
superscript character code does not exist, a question mark
will be returned for that character.
Usage
supsc(x)
Value
The superscript version of the string passed to the function,
if one exists. Otherwise, a question mark will be returned.
