here is a raku regex (see https://docs.raku.org/language/regexes#Unicode_properties https://docs.raku.org/language/regexes#Unicode_properties) "Dž" ~~ /<:Lt>/ #｢Dž｣ (matches) "Dž" ~~ /<:Lu>/ #Nil (doesn't match) Lt = Titlecase_Letter Lu = Uppercase_Letter raku regex are a step improvement over the original perl5 regex which is used in most current languages (both regex engines were designed by Larry Wall - raku is perl6 with a new name) deep support for Unicode and Graphemes makes raku almost unique in its support for Unicode properties within this new regex 2.0 (I hear that Swift is also strong in this area) here is a great blog series by Paweł bbkr Pabian that explains all these unicode things in a very unserstandable way https://dev.to/bbkr/utf-8-regular-expressions-20h0 https://dev.to/bbkr/utf-8-regular-expressions-20h0
