BCP47 should be used to identify languages instead of ISO 639-1.
See https://tools.ietf.org/html/bcp47
One of the problems with using ISO 639-1 2 letter codes is that it does not adequately address the handling of Chinese. For example, in ISO 639-1 Chinese is represented as zh. This code cannot indicate whether the writing system is Simplified Chinese or Traditional Chinese. The BCP47 standard clearly indicates which writing system is in use. In this case if Simplified Chinese was being used the code would be zh-Hans and for Traditional Chinese it would be zh-Hant.
