I can't reproduce the problem here. I processed your
source file using XeLaTeX, opened the resulting PDF
in Adobe Acrobat Reader 9, copied the entire text,
pasted it into WordPad, selected each superscript
in turn, and used each in a Ctrl-F "Find" dialogue :
only the superscript was found in each case, not
the similar-looking normal character.
