<pre>As per <a href="https://developer.apple.com/reference/corefoundation/1666963-cflocale?language=objc">https://developer.apple.com/reference/corefoundation/1666963-cflocale?language=objc</a> , CFLocale is using BCP-47 language tags. Our Mac implementation is relying on CFLocaleCopyPreferredLanguages() which does return BCP-47 language tags.
However, we then call httpStyleLanguageCode() on them which alters their format (and lower cases them).</pre>
