Seems like it's not the right replacement:

No special env vars set:
```
KLocale::global()->languageList()  ("de", "en_US")
KLocalizedString::availableApplicationTranslations() = ("pt_BR", "nds", "kk", "ga", "mr", "km", "ko", "en_US", "ca", "gl", "is", "it", "el", "nb", "tr", "ro", "pl", "es", "et", "en_GB", "eu", "ja", "ru", "nl", "cs", "nn", "pt", "ar", "ug", "hi", "lt", "da", "lv", "uk", "zh_CN", "zh_TW", "fi", "de", "sk", "hr", "sl", "hu", "bg", "fr", "ca at valencia", "sv")
QLocale().uiLanguages() = ("de-DE")
KConfig(kf5_all_languages).groupsList() = ("ca at valencia", "ln", "de", "tw", "lo", "ty", "lt", "lv", "ug", "uk", "pt_BR", "dz", "mg", "mh", "mi", "ur", "mk", "ml", "mn", "mo", "uz", "mr", "ms", "mt", "el", "en", "crh", "eo", "my", "be at latin", "es", "et", "eu", "vi", "na", "nb", "nd", "ne", "vo", "ng", "fa", "nl", "nn", "csb", "nr", "fi", "fj", "sr at ijekavian", "nv", "wa", "fo", "ny", "fr", "oc", "fy", "wo", "ga", "sr at latin", "hne", "om", "gd", "or", "os", "gl", "uz at cyrillic", "gn", "gu", "xh", "gv", "zh_HK", "pa", "nso", "pi", "ha", "pl", "he", "hi", "mai", "ps", "pt", "ho", "hr", "hu", "yi", "hy", "hz", "yo", "ia", "id", "ie", "aa", "ik", "ab", "qu", "ae", "za", "io", "af", "nds", "is", "ven", "it", "iu", "zh", "am", "ar", "as", "ja", "sr at ijekavianlatin", "x-test", "ay", "zu", "az", "rn", "ro", "en_US", "ba", "ru", "be", "rw", "bg", "bh", "bi", "jv", "bn", "sa", "bo", "sc", "sd", "br", "se", "bs", "sg", "si", "ka", "sk", "sl", "zh_CN", "sm", "ast", "sn", "so", "sq", "ki", "sr", "bn_IN", "ca", "ss", "kk", "st", "kl", "su", "km", "sv", "kn", "ce", "sw", "ko", "ch", "ks", "rom", "ku", "kv", "kw", "ta", "co", "ky", "zh_TW", "te", "cs", "tg", "cu", "th", "cv", "ti", "hsb", "la", "lb", "tk", "cy", "tn", "to", "en_GB", "li", "tr", "da", "ts", "tt", "dsb")
```

With LANGUAGE="de_DE"

```
KLocale::global()->languageList()  ("de", "en_US")
KLocalizedString::availableApplicationTranslations() = ("sv", "pt_BR", "ca at valencia", "kk", "ga", "mr", "km", "ko", "en_US", "nds", "ca", "gl", "is", "it", "el", "nb", "tr", "ro", "en_GB", "pl", "es", "et", "eu", "ja", "ru", "nl", "cs", "nn", "pt", "ar", "ug", "hi", "lt", "da", "zh_CN", "zh_TW", "lv", "uk", "fi", "de", "sk", "hr", "sl", "hu", "bg", "fr")
QLocale().uiLanguages() = ("de-DE")
KConfig(kf5_all_languages).groupsList() = (...)
```

With LANGUAGE="en_GB:de_DE"
```
KLocale::global()->languageList()  ("en_GB", "de", "en_US")
KLocalizedString::availableApplicationTranslations() = ("ga", "nds", "kk", "mr", "km", "ko", "ca", "gl", "pt_BR", "is", "it", "el", "nb", "tr", "ro", "en_US", "pl", "es", "et", "eu", "ja", "ru", "nl", "cs", "nn", "pt", "ar", "en_GB", "ug", "hi", "lt", "da", "lv", "uk", "fi", "de", "sk", "hr", "sl", "hu", "bg", "fr", "ca at valencia", "zh_CN", "zh_TW", "sv")
QLocale().uiLanguages() = ("en-GB", "de-DE")
```

With LANGUAGE="de_DE:en_GB"
```
KLocale::global()->languageList()  ("en_GB", "de", "en_US")
KLocalizedString::availableApplicationTranslations() = ("mr", "km", "ko", "nds", "en_GB", "ca", "gl", "is", "it", "el", "nb", "tr", "ro", "pl", "es", "et", "eu", "ja", "ru", "nl", "cs", "nn", "zh_CN", "zh_TW", "pt", "ar", "ca at valencia", "ug", "hi", "lt", "da", "lv", "uk", "fi", "de", "sk", "hr", "sl", "hu", "bg", "pt_BR", "fr", "sv", "en_US", "ga", "kk")
QLocale().uiLanguages() = ("de-DE", "en-GB")
KConfig(kf5_all_languages).groupsList() = (...)
```
This one is very confusing, why is en_GB still the highest priority according to KLocale::global()->languageList()? Maybe it is reading some config file where I set that?

With LANGUAGE="fr_FR"

```
KLocale::global()->languageList()  ("de", "en_US")
KLocalizedString::availableApplicationTranslations() = ("et", "eu", "ja", "ru", "nl", "cs", "nn", "pt", "en_GB", "ar", "ca at valencia", "ug", "hi", "lt", "da", "lv", "uk", "fi", "de", "sk", "hr", "sl", "zh_CN", "zh_TW", "hu", "bg", "fr", "sv", "nds", "ga", "kk", "mr", "km", "ko", "pt_BR", "ca", "gl", "en_US", "is", "it", "el", "nb", "tr", "ro", "pl", "es")
QLocale().uiLanguages() = ("fr-FR")
```

Even more confusion, LANGUAGE now has no effect on KLocale::global()->languageList()

With LANG=fr_FR
```
KLocale::global()->languageList()  ("fr", "en_US")
KLocalizedString::availableApplicationTranslations() = ("sk", "hr", "sl", "hu", "bg", "pt_BR", "fr", "sv", "en_US", "kk", "ga", "km", "mr", "ko", "en_GB", "ca", "gl", "is", "it", "el", "nb", "tr", "ro", "pl", "es", "et", "eu", "ja", "ru", "nl", "cs", "nn", "zh_CN", "zh_TW", "pt", "ar", "ca at valencia", "nds", "ug", "hi", "lt", "da", "lv", "uk", "fi", "de")
QLocale().uiLanguages() = ("fr-FR")
```

LANG seems to work where LANGUAGE doesn't.

I have no idea what's going on here, I need some feedback from someone with more I18N experience.

However, QLocale().uiLanguages() seems to be almost the right replacement if we append en_US and convert it from de-DE to de_DE. However, the order is not the same...
