tonihei 1ddac0c703 Remove API version dependency of Util.normalizeLanguageCode ... We previously used Locale.fromLanguageTag and then toLanguageTag to automatically filter out invalid tags and to replace deprecated tags. However, this only works for API 21+. This change does no longer rely on the platform methods and instead: 1. Keeps invalid tags as they are. This may help if developers rely on non-spec-complaint language tags (for example, #6681). 2. Adds a list of deprcated tags and their modern replacements to our code 3. Normalizes some short codes that have been superseded by macrolanguage codes by their macrolanguage equivalent.
