# 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).
#newline_default lf any anycrlf
# PCRE2 and Perl disagree about the characteristics of certain Unicode
# characters. For example, 061C was considered by Perl to be Arabic, though
# it was not listed as such in the Unicode Scripts.txt file for Unicode 8.
# However, it *is* in that file for Unicode 10, but when I came to re-check,
# Perl had changed in the meantime, with 5.026 not recognizing it as Arabic.
# 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.
