The HasGraphic(s) command determines whether s has a graphic character. Graphic characters consist of the alphanumeric characters and the punctuation characters. (For more information, see HasAlphaNumeric and HasPunctuation.)

If s has a graphic character, HasGraphic returns true. Otherwise, false is returned.

The StringTools[HasGraphic] command is thread-safe as of Maple 15.
