/**
  * Translates a message to the specified language.
  * Starting from version 1.0.2, this method supports choice format (see {@link CChoiceFormat}),
  * i.e., the message returned will be chosen from a few candidates according to the given
  * number value. This feature is mainly used to solve plural format issue in case
  * a message has different plural forms in some languages.
  * @param string message category. Please use only word letters. Note, category 'yii' is
  * reserved for Yii framework core code use. See {@link CPhpMessageSource} for
  * more interpretation about message category.
  * @param string the original message
  * @param array parameters to be applied to the message using <code>strtr</code>.
  * Starting from version 1.0.2, the first parameter can be a number without key.
  * And in this case, the method will call {@link CChoiceFormat::format} to choose
  * an appropriate message translation.
  * @param string which message source application component to use.
  * Defaults to null, meaning using 'coreMessages' for messages belonging to
  * the 'yii' category and using 'messages' for the rest messages.
  * @param string the target language. If null (default), the {@link CApplication::getLanguage application language} will be used.
  * This parameter has been available since version 1.0.3.
  * @return string the translated message
  * @see CMessageSource
