Pass in the `ucp' option:

ucp
    Specifies that Unicode Character Properties should be used when 
    resolving \B, \b, \D, \d, \S, \s, \W and \w. Without this flag, only 
    ISO-Latin-1 properties are used. Using Unicode properties hurts 
    performance, but is semantically correct when working with Unicode 
    characters beyond the ISO-Latin-1 range.
