1 # This set of tests is not Perl-compatible. It checks on special features 2 # of PCRE2's API, error diagnostics, and the compiled code of some patterns. 3 # It also checks the non-Perl syntax that PCRE2 supports (Python, .NET, 4 # Oniguruma). There are also some tests where PCRE2 and Perl differ, 5 # either because PCRE2 can't be compatible, or there is a possible Perl 6 # bug. 7 8 # NOTE: This is a non-UTF set of tests.
