Commit upstream pcre-8.39.tar.bz2
[pcre3.git] / 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. --/
