Multilingual Support in QuickLook

QuickLook Core Application (QL Main Program):

• QuickLook implements multilingual support using separate XML files for each supported language.
• All UI strings, messages, and text displayed by QuickLook are stored in these XML language files.
• When adding a new feature, all supported language files must be updated; every string key must be translated in every language’s XML. Missing translations are not allowed.
• On startup, QuickLook loads the language file corresponding to the user’s system locale, ensuring a consistent and complete localized UI.

QuickLook Plugins:

• Plugins also implement localization using XML language files, following the same structure and requirements as the main program.
• Each plugin must maintain its own language files for every supported language, covering all displayed UI strings and messages.
• Any addition of new strings or features in a plugin requires translating every string into all supported languages and updating the XML files accordingly.
• The plugin loads the appropriate XML language file at runtime based on the system or QuickLook's selected language.

Important Note: When implementing or updating multilingual support in QuickLook or its plugins, all supported languages must be present and fully localized in the XML files. Partial or missing translations are not permitted.
