How does wide-character warnings affect performance or memory usage?

In Perl, wide-character warnings can impact performance and memory usage when dealing with string operations, particularly with large strings or when processing significant volumes of data. When wide-character warnings are enabled, Perl performs additional checks to ensure that the strings are correctly encoded, which can slow down string manipulation and increase memory overhead.


        # Enable wide-character warnings
        use warnings qw(utf8 wide);

        # Example of wide-character
        my $string = "This is a test string with wide character: ö";
        print $string;
