I do a lot of editing work on texts containing some Latin letters, e.g. alpha, kappa, etc, which I insert using the "Insert" > "symbol" command. Very often, however, after receiving the documents back from colleagues who have worked on them (also in Word), some or all of the symbols have been replaced with a little square with a question mark in the middle (even though the symbols themselves were not altered by my colleagues). This wastes so much time, it's driving me up the wall. Does anyone know how to fix this? I cannot save them as text files as I need to retain embedded field codes.
Thank you!
