When retrieving subtitles, even if they are named with two characters, the languageCode returned is always a three character code. This makes it difficult with Java and in particular Android to correctly detect the language code being used and matching up to the locale.
Ideally a two character code would be preferable for comparison instances. Another option is to include the 2 character and the 3 character code in the output. This way a lookup table doesn't need to be maintained which can change as the ISO codes change over the years.
