StringTools

 HasGraphic
 determine if a string has a graphic character

 Calling Sequence HasGraphic(s)

Parameters

 s - string; string to test

Description

 • 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.
 • All of the StringTools package commands treat strings as (null-terminated) sequences of $8$-bit (ASCII) characters.  Thus, there is no support for multibyte character encodings, such as unicode encodings.
