This file contains ambiguous Unicode characters

This file contains Unicode characters that might be confused with other characters. If you think that this is intentional, you can safely ignore this warning. Use the Escape button to reveal them.

# 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.
