    tables for:

       * Candidates for Inclusion in Identifiers
       * Candidate Characters for Exclusions from Identifiers
       * Recommended Scripts


    UAX#9 Unicode Bidirectional Algorithm

    The main changes are the addition of:

       * a section on Bidi Conformance Testing
       * the Bidi_Class BN to Rule X6 (removing certain characters from
         Bidi processing)
       * a clause in HL6 providing for mirroring of R and AL characters in
         certain circumstances
