Hi!

There seems to be a bug in Symfony\Component\Translation computing the fallbacks in method computeFallbackLocales. Perhapes someone can confirm or correct me?

• We use a valid ICU language selector e.g de_AT_VIENNA and we have a message file for de, de_AT and de_AT_VIENNA containing a valid translation
• locale is de_AT_VIENNA
• the lookup ID is missing in de_AT_VIENNA, so fallback is triggered
• the fallback is computed in the order first de, then de_AT, what is imo wrong, it has to be de_AT followed by de corresponding to ICU usage

I would just change the array_unshift to a normal append operation

Did I miss something? This seams to be since a long time ...

changed line arround line 441 of Translator.php to:

        if (null !== $locale) {
            // m.boeck: wrong order in fallback - bug in symfony
            $locales[] = $locale;
        }

removing the array_unshift operation. For me it works.

Thats also in the 4.x branch.
