Utf 8 manipulation
If you want to manipulate UTF-8 string, you need enable utf8 pragma in all your script which contains UTF-8 string.
use Mojolciious::Lite;
use utf8;
my $name = "おおつか たろう";This is basic convention in Perl, and you remember to save the srcipt as UTF-8.
In Mojolicious, all string which contains request is converted to Perl internal string.
# Parameter value of "foo" is Perl internal string
my $foo = $self->req->param('foo');If you save it to data storage such as RDBMS, you must encode it to byte string by encode() of Encode.
use Encode 'encode';
$foo = encode('UTF-8', $foo);Generally, you can use the DBD feature of converting Perl internal string to byte string if DBD provide that feature.
# SQLite
my $dbh = DBI->connect($data_source, undef, undef, {sqlite_unicode => 1});
# MySQL
my $dbh = DBI->connect($data_source, $user, $password, {mysql_enable_utf8 => 1});It is good that this setting is done when connecting to database, not after connecting to database.
In HTML rendering, Perl internal string is automatically converted to UTF-8 byte string, and it is good that Character set is specify in HTML header by "http-equiv" attribute.
get '/' => 'index';
app->start;

# Load JSON configuration file
plugin 'json_config';When you render JSON data, the data is converted from Perl internal string to UTF-8 byte string, so the strings which data contains must be UTF-8.
# JSON rendering
$self->render_json($data);In test script, you enable utf8 pragma, and save the script as UTF-8.
use Test::More tests => 3;
use utf8;
my $t = Test::Mojo->new(...);If you want to contain UTF-8 byte string in query string of URL, use url_escape() of Mojo::ByteStream. b() is shortcut of Mojo::ByteStream->new.
# Test get request
my $url = '/foo?name=すずき';
$url = b($url)->url_escape->to_string;
$t->get_ok($url)
->status_is(200)If you want to post form data for test, specify the Character set as the second argument. All parameter names and values are converted from Perl internal string to byte string.
# Test post request
$t->post_form_ok('/foo', 'UTF-8' => {name => 'すずき'})
->status_is(200)
