For example, 'de' might suffice for tagging an email written in German, while 'de-CH-1966' is probably unnecessarily precise for such a task. Avoid using subtags that add no distinguishing information about the content. For example, the script subtag in 'en-Latn-US' is generally unnecessary, since nearly all English texts are written in the Latin script.
