如何从第一个preferredLanguages中获取Windows区域设置代码？
目前，它返回我12（十进制），这不对应于任何windows区域设置（请参阅：https://learn.microsoft.com/en-us/openspecs/office_standards/ms-oe376/6c085406-a698-4e12-9d4d-c3b0ee3dbc4a）

#include <CoreFoundation/CoreFoundation.h>

int main() {
    CFArrayRef preferredLanguages = CFLocaleCopyPreferredLanguages();

    if (CFArrayGetCount(preferredLanguages) > 0) {
        CFStringRef firstLanguage = CFArrayGetValueAtIndex(preferredLanguages, 0);
        CFLocaleIdentifier localeIdentifier = CFLocaleCreateCanonicalLanguageIdentifierFromString(NULL, firstLanguage);
        uint32_t windowsLocaleCode = CFLocaleGetWindowsLocaleCodeFromLocaleIdentifier(localeIdentifier);

        printf("Windows locale code %d.\n", windowsLocaleCode);
    } else {
        printf("No preferred languages found.\n");
    }

    CFRelease(preferredLanguages);
    return 0;
}
