/**
* 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.
