The HasSpace(s) command determines whether s has any space characters.

A space character is any one of the following:

If s is a space character, HasSpace 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.

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

For more information on thread safety, see index/threadsafe.
