Translate fileinput don't work with 'pt-BR' and 'zh-TW'

[RochaXavier]

I try to translate the plugin with yii2 widget, but it doesn't work:

    $form->field($model, 'arquivos')->widget(FileInput::className(), [
        'options' => [
            'multiple' => true
        ],
        'language' => 'pt-BR',
        'pluginOptions' => [
            'maxFileCount' => 10
        ]
    ]);

When I try with another language it works, only 'pt-BR' and 'zh-TW' don't.

Looking at the network panel, the file is loaded correctly "/web/assets/d32e62c3/js/locales/pt-BR.js" but the script wrinten by widget sets language to "pt" as follows.

<script>window.fileinput_66e1ded4 = {"maxFileCount":10,"language":"pt","resizeImage":false,"autoOrientImage":true,"theme":"fas","purifyHtml":true};
</script>

Yii version: 2.0.19 Jquery version: 3.3.1 bootstrap-fileinput version: 5.0.3

Hi guys! I'm facing the same problem trying to set up 'pt-BR' language. It appears to be the same related by @RochaXavier.

My app is currently set up with config Yii::$app->language => 'pt-BR' according to Yii2 Guide - i18n.

Some tests:

• config Yii::$app->language => 'pt-BR' renders 'en'
• config Yii::$app->language => 'pt-br' (which according to the Yii2 guide is incorret) renders 'pt' (from Portugal not Brazil)
• pass ->widget(FileInput::class, ['language' => 'pt-BR', ...] still renders 'en'
• pass ->widget(FileInput::class, ['language' => 'pt-br', ...] renders 'pt' (from Portugal not Brazil)
• pass ->widget(FileInput::class, ['language' => 'pt', ...] renders 'pt' (from Portugal not Brazil)
• pass ->widget(FileInput::class, ['language' => 'br', ...] renders 'en'

Is that a bug, or what am I doing wrong? @RochaXavier, did you find the solution?

Thank you!
