Damus is using Apple’s recently deprecated locale-specific .strings and .stringsdict file formats. I have a PR open that converts Nos.social from .strings to Apple’s new multilingual .xcstrings file format (effectively JSON) which was possible because Crowdin supports that format, but I haven’t done it for Damus yet because Transifex doesn’t support it yet. In any case, if this were to be done, some platform agnostic format should be used.
