StringTools

 HasPunctuation
 determine if a string contains a punctuation character

 Calling Sequence HasPunctuation(s)

Parameters

 s - string; string to test

Description

 • The HasPunctuation( s ) command determines whether s contains a punctuation character. Punctuation characters are printable characters, other than whitespace, for which neither IsControlCharacter nor IsAlphaNumeric returns true.
 • If s contains a punctuation character, HasPunctuation 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.
