I can hazard a guess. If you Google as I suggested it seems
that rdquor is some sort of quote symbol. Where smart quotes are
used in Word, I have seen that cause problems with the HTML. My
guess is that the Word document has some sort of quotes that on
import into RH have been translated into what you see, that RH6
could deal with that but not the new editor in RH7.
Look at the code. Can you not use a multip file find and
replace tool to fix the code?
