Wingdings is one way to do what you want.
To see what I mean Click START >PROGRAMS >ACCESSORIES >SYSTEM TOOLS >CHARACTER MAP
This utility lets you see all the Characters within a Character Set (Font)
If you then scroll down to WINGDINGS you'll see numbers in circles, along with a lot of other useful characters.
I your're not sure how to get them into Word, Click HELP, it explains it better than I.
