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.

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