It would be nice to have improved fallback langugage. E.g. I have the string in the locale de but I don't have the string in the locale de_CH. Actually, if the user uses locale de_CH, the string in the default langugae (= English) is used but it is better for user to use the string of locale de instead. Then, if no string for locale de_CH either for locale de exists, the English string is used.

Is it possible? It would be nice to have also a possibility to define this 'fallback waterfall' but the default gettext behaviour is enough I think: (country specific locale, e.g. 'de_CH') -> (general locale, e.g. 'de') -> (the default language = English).
