## Issue
656 Automatic language detection can't recognize de-DE as de
## Note
We do fallback to the main language, but seems like the code got lost ... not sure when, but probably during the CN/TW or PT-BR support. The refactor in 81e47300 still did that, but the refactor was reverted due to some compilation issue (should revisit that someday).
## Change
Put back equivalent code.
