How does test discovery (prove) interact with Unicode and encodings?

Test discovery in Perl using the 'prove' utility interacts with Unicode and encodings in a specific manner. When you are working with test files that contain Unicode characters, it's essential to ensure that both your test scripts and the environment are configured to handle the desired encodings appropriately.

One common approach is to specify the encoding at the beginning of your test files. In Perl, you can declare the encoding using the encoding pragma. This helps 'prove' and other tools understand how to read the file correctly:

#!perl use strict; use warnings; use utf8; # Enable UTF-8 encoding use Test::More; # A sample test for a Unicode string my $unicode_string = "Unicode test: π (pi)"; is($unicode_string, "Unicode test: π (pi)", "Unicode string matches"); done_testing();

Unicode Perl prove test discovery encodings UTF-8
