      Determines which Unicode characters this lexer allows for identifiers.
      The possible values are:

      * ``none`` -- only the ASCII letters and numbers are allowed. This
        is the fastest selection.
      * ``basic`` -- all Unicode characters from the specification except
        category ``Lo`` are allowed.
      * ``full`` -- all Unicode characters as specified in the C# specs
        are allowed.  Note that this means a considerable slowdown since the
        ``Lo`` category has more than 40,000 characters in it!
