These handle the words in the text.

Math identifiers: E  m  c .

The page number; presumably  1 .


> LKHLTI+CMR7                          Type 1C           yes yes no      10  0

The superscripted  2 .

Because anything written in math mode obeys a different set of typesetting rules to what is used in ordinary text. This involves spacing, positioning and sizing of super- and subscripts as well as choice of font face for each class of character or symbol. This is what makes TeX output look so much more attractive than what any other software produces.
 
To change things, you'll need to study the  mathspec  or  unicode-math  packages, if I've got the names correct. Otherwise study the LaTeX Companion, for ways to handle Math Alphabets using non-XeTeX methods, which should still work, but with a limited range of fonts.
