Changes for version 0.31 - 2003-11-16

  • Illegal code points (surrogate and noncharacter; they are definitely ignorable) will be distinguished from NULL ("\0"); but porting is not successful in the case of ((Pure Perl) and (Perl 5.7.3 or before)). If perl 5.6.X is used, XSUB may help it in place of broken CORE::unpack('U*') in older perl.
  • added illegal.t and illegalp.t.
  • added XSUB edition (EXPERIMENTAL) where some functions are implemented in XSUB (Pure Perl edition is also supported.)
