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.
