How does subtesting and table-driven tests interact with Unicode and encodings?

In Perl, subtests and table-driven tests can handle Unicode and various encodings effectively, but there are some nuances to consider. When you're conducting subtests, make sure that you are aware of how strings are encoded, especially if your tests involve non-ASCII characters. If you're working with UTF-8, ensure that your input strings are properly encoded before running your tests.

Here's a simple example of using subtests with UTF-8 encoded strings:

use Test::More; use Encode qw(decode); # Ensure the output is UTF-8 binmode STDOUT, ':utf8'; my $utf8_str = "Hello, 世界"; # A string containing Unicode characters subtests 'UTF-8 Tests' => sub { is(decode('UTF-8', $utf8_str), "Hello, 世界", 'Check Unicode String'); is(length($utf8_str), 13, 'Check length of Unicode String'); }; done_testing();
