Creating a PDF with Embedded Fonts for MS Word

Why is it important to embed fonts when creating a PDF?
“Embedding fonts” ensures that all of the font information used to make your document look the
way it does is stored in the PDF file. So, no matter what fonts a balloter (or reader) has on their
computer, they’ll be able to see the file as you intended it to be seen. If you don’t embed fonts,
Adobe AcrobatTM or an equivalent PDF creator will make its best guess at font substitution using
whatever fonts are available on the balloter’s computer. Substitution can result in significant
differences between your intended output and what the balloter observes (particularly with
symbol fonts), so it is best to have the fonts embedded.
