The predefined abbreviation of a negated character class of all ASCII white space characters is \S, which is the same as [^ \t\r\n\f]. Note that:

\t - Horizontal tab (ASCII 0x09) 
\n - Linefeed or newline (ASCII 0x0A)
\f - Form feed (ASCII 0x0C)
\r - Carriage return (ASCII 0x0D)

\S will match any characters except ASCII white space characters.
