This class is a transparent base class for I18n and should not be accessed directly.
Internationalization (i18n) class. Provides language loading and translation methods without dependencies on gettext.
Typically this class would never be used directly, but used via the __() function, which loads the message and replaces parameters:
// Display a translated message
echo __('Hello, world');
// With parameter replacement
echo __('Hello, :user', [':user' => $username]);

array(0) Returns translation of a string. If no translation exists, the original string will be returned. No parameters are replaced.
