# This set of tests checks the API, internals, and non-Perl stuff for UTF
# support, including Unicode properties. However, tests that give different
# results in 8-bit, 16-bit, and 32-bit modes are excluded (see tests 10 and
# 12).

# PCRE2 and Perl disagree about the characteristics of certain Unicode
# characters. For example, 061C is considered by Perl to be Arabic, though
# is it not listed as such in the Unicode Scripts.txt file, and 2066-2069 are
# graphic and printable according to Perl, though they are actually "isolate"
# control characters. That is why the following tests are here rather than in
# test 4.
