# 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. /^[\p{Arabic}]/utf \= Expect no match \x{061c} No match /^[[:graph:]]+$/utf,ucp \= Expect no match \x{61c} No match \x{2066} No match \x{2067} No match \x{2068} No match \x{2069} No match /^[[:print:]]+$/utf,ucp \= Expect no match \x{61c} No match \x{2066} No match \x{2067} No match \x{2068} No match \x{2069} No match /^[[:^graph:]]+$/utf,ucp \x{09}\x{0a}\x{1D}\x{20}\x{85}\x{a0}\x{61c}\x{1680} 0: \x{09}\x{0a}\x{1d} \x{85}\x{a0}\x{61c}\x{1680} \x{2028}\x{2029}\x{202f}\x{2065}\x{2066}\x{2067}\x{2068}\x{2069} 0: \x{2028}\x{2029}\x{202f}\x{2065}\x{2066}\x{2067}\x{2068}\x{2069} /^[[:^print:]]+$/utf,ucp \x{09}\x{1D}\x{85}\x{61c}\x{2028}\x{2029}\x{2065}\x{2066}\x{2067} 0: \x{09}\x{1d}\x{85}\x{61c}\x{2028}\x{2029}\x{2065}\x{2066}\x{2067} \x{2068}\x{2069} 0: \x{2068}\x{2069} # Perl does not consider U+180e to be a space character.
