You didn't give us a lot to go on, but my first guess is that the style that
is applied to bulleted text (possibly List Paragraph) is formatted as a
symbol font (Wingdings, Webdings, Symbol, etc.). Check the style, and if it's
a strange font, modify the style to use your standard font.
If that isn't it, post back with more information (what version of Word, how
you're applying bullets, etc.).
