Exactly how it is done will vary from application to application & version to version, but for most WORD versions, open the document & click Tools -> Options, then look for the "Saves" tab. Somewhere under "Saves" there will be something about "save with fonts embedded". Mark it and RE-SAVE THE DOCUMENT BEFORE MAKING THE PDF. (Often there is an option to only include the characters in use - it makes the file a bit smaller and works fine as long as the author is absolutely positive that no one will have to do any touch-up editing to the document. Even if the editor, such as a section chair or the SAS Print Center, has the font that was used, the PDF file will not allow editing unless the full font set is embedded.)
