The StrongHelp manual states that \s is equivalent to '\t\x0A '. The
quotes are important here and indicate that \s represents a set.

A set is essentially an abbreviated way of writing a sequence of OR's.
Based on the StrongHelp page: \s  =  '\t\x0A '  =  \t | \x0A | " "

In reality it's: \s  =  White  =  '\x09-\x0D\x20\xA0'

Cheers,
Fred.
