I have a problem inserting a non-Word text document into my Word document because in the older document the exponents were considered as having a smaller size font than normal characters, contrary to Word practice.
As a result exponents are poorly rendered ; the obvious correction is to reset the font size for each individual exponent character, but as there are hundreds of them it is a bit tedious to do it by hand.
Any ideas ?

It's not exactly clear what you mean by this. I'd have thought the norm was to use superscripts - which is how you'd do it in Word, too.

Any solution is likely to be tedious. Mine would be to copy the information and paste as plain text. Then I would go through, manually, and apply the superscript, perhaps using a character style.
