Dear Nina,
allow me to offer some opinion. I believe your problem has to do with the fonts. You have to ensure that the two computers have the same fonts installed. The best is to use Unicode fonts nowadays. Hope that helps.

I have a Mac OS X, and use for my Pali: PCharter, but I noticed that the diacritical signs did not work when sending a Word attachment to another computer. The signs did not come out. I do not easily understand technical instructions. I guess it must be PCharter but hard for me to change it. I use it in all my writings.
