I have also provided few default predicated to use. They are in string_funct.hpp header and can be accessed via following helper functions. if_isclassified( Type, Locale ) if_isspace( Locale ) if_isfrom( Seq ) all of them return instance to specific functor. isclassified was suggested by Genny Prota, isspace is just instantiation if isclassified with std::ctype_base::space as the type. isfrom functor lets you specify a range over set of elements you want to trim-out. I have used the same naming scheme as in standard, so all variants which accept predicate have _if suffix. A have left original variants ( those without suffix ) and they are mapping to isspace functor.
