How has support for use utf8 and open layers changed across recent Perl versions?

Over the years, Perl has seen significant enhancements in its support for UTF-8 and its use of open layers. Starting from version 5.8, Perl introduced native support for UTF-8 encoding, which has streamlined the handling of international text. This laid the groundwork for better global language support.

With Perl 5.14, the 'use utf8' pragma became more robust, allowing developers to directly utilize UTF-8 encoded scripts. This ease of use has made Perl a preferred choice for applications requiring multilingual support. Moreover, the open layers, particularly with Perl’s IO layer improvements, have facilitated seamless file handling and input/output operations with UTF-8 encoded data.

In Perl 5.24, further optimizations improved the performance of text encoding operations, making it simpler for developers to work with large datasets in various languages without performance drawbacks. Additionally, the new Unicode features in recent releases have enhanced regular expression capabilities for working with Unicode characters.

Overall, the continuous enhancements in UTF-8 and open layers make Perl a powerful tool for modern web and application development in diverse linguistic environments.
