 /**
  * Detects preferred locales from a console request by looking at certain
  * environment variables. The environment variables may be present or not
  * depending on your system. If multiple variables are present the following
  * hierarchy is used: `'LANGUAGE'`,  `'LC_ALL'`, `'LANG'`.
  *
  * The locales of the `'LC_ALL'` and the `'LANG'` are formatted according
  * to the posix standard: `language(_territory)(.encoding)(@modifier)`.
  * Locales having such a format are automatically canonicalized and transformed
  * into the `Locale` class' format.
  *
  * @link http://www.linux.com/archive/feature/53781
  * @param \lithium\console\Request $request
  * @return array Preferred locales in their canonical form (i.e. `'fr_CA'`).
