How does capturing groups interact with Unicode and encodings?

Capturing groups in Perl regular expressions interact with Unicode and encodings in a way that allows for sophisticated text processing and pattern matching across various character sets. When working with Unicode data, it's essential to ensure that your regular expressions are correctly configured to handle multibyte characters. This ensures that capturing groups can accurately match and extract the desired portions of the text, regardless of the encoding used.

Here’s an example of using capturing groups with Unicode in Perl:

$text = "こんにちは世界"; // "Hello World" in Japanese if ($text =~ /(\p{Hiragana})(\p{Kanji})/) { print "Matched: $1 and $2\n"; // Outputs: Matched: こんにちは and 世界 }
