How does regex with Unicode properties interact with Unicode and encodings?

Regex with Unicode properties in Perl allows you to perform pattern matching on Unicode strings using specific character properties such as categories (e.g., letters, digits) or scripts (e.g., Latin, Cyrillic). This feature is beneficial when working with internationalized text.

When you use regex with Unicode properties, it's essential to ensure that your text is properly encoded in UTF-8, as Perl's regex engine will interpret the characters based on their Unicode definitions.

Here is a simple example demonstrating the use of Unicode properties in a Perl regex to match Unicode letters:

# Example Perl code using Unicode properties use strict; use warnings; use utf8; my $string = "Café 123"; # Contains a Unicode character (é) if ($string =~ /\p{L}+/) { # Matches any Unicode letter print "Matched a Unicode letter!\n"; }
