constant Unicode::PREG_CLASS_WORD_BOUNDARY in Plug 7

Matches Unicode characters that are word boundaries.

Characters with the following General_category (gc) property values are used as word boundaries. While this does not fully conform to the Word Boundaries algorithm described in http://unicode.org/reports/tr29, as PCRE does not contain the Word_Break property table, this simpler algorithm has to do.

  • Cc, Cf, Cn, Co, Cs: Other.
  • Pc, Pd, Pe, Pf, Pi, Po, Ps: Punctuation.
  • Sc, Sk, Sm, So: Symbols.
  • Zl, Zp, Zs: Separators.

Non-boundary characters include the following General_category (gc) property values:

  • Ll, Lm, Lo, Lt, Lu: Letters.
  • Mc, Me, Mn: Combining Marks.
  • Nd, Nl, No: Numbers.

Note that the PCRE property matcher is not used because we wanted to be compatible with Unicode 5.2.0 regardless of the PCRE version used (and any bugs in PCRE property tables).
