testdata/testinput2

   1 /-- This set of tests is not Perl-compatible. It checks on special features
   2     of PCRE's API, error diagnostics, and the compiled code of some patterns.
   3     It also checks the non-Perl syntax the PCRE supports (Python, .NET,
   4     Oniguruma). Finally, there are some tests where PCRE and Perl differ,
   5     either because PCRE can't be compatible, or there is a possible Perl
   6     bug.
   7
   8     NOTE: This is a non-UTF set of tests. When UTF support is needed, use
   9     test 5, and if Unicode Property Support is needed, use test 7. --/
