If you need to send a document not knowing if one or more of the fonts that you use are installed in the PC of the recipient, you can embed these fonts to your document.

Go to the Options of Word, in the “Save” section, and put a checkmark at “Embed fonts in the file.”

Check also the last option, “Do not embed common system fonts,” since you don’t need to increase the size of your document without reason.

Note that only True Type and Open Type fonts can be embedded.

Enjoy!
