Use Standard Character Sets
Some developers use symbolic fonts, such as Wingdings, to convey information visually. Common examples include emoticons, the Wingding character for scissors to indicate where one should cut a form, and the Wingding telephone character, which is often used to flag a telephone number.
Screen readers and other types of assistive technology cannot read these symbolic or non-standard character fonts, so you should use only ASCII (American Standard Code for Information Interchange) or Unicode characters in your Flash applications. If you would like to convey the information indicated by a Wingding character, use a graphic image instead and provide an appropriate accessible name.
The best way to test to be sure that your application does not include character sets that are unreadable by AT is to test your application with AT running. The VHA Section 508 checkpoints related to character sets are available in a separate window by selecting the link that follows:
