Maybe, maybe not. If the superscript can be expressed using superscript 
characters (e.g., SUPERSCRIPT LATIN SMALL LETTER N U+207F), then the 
superscripting _can_ be expressed in plain text and hence also in HTML.
Whether it would be wise or recommendable to do so is a different matter.

Thus, there are _three_ ways to deal with superscripts and subscripts:
1) use markup that means superscripting or subscripting
2) use a style sheet (e.g., setting vertical-align and font-size);
    this naturally requires some markup that makes the piece of text
    an element
3) use a superscript or subscript character (directly or using a
    a character or entity reference), when applicable
