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