The $locale and $dictionary arrays are stored in files in the config/locales/ and in app/locales/<page>/ directories. It seems that the assumption is made that the locale and the language will be coordinated. In Finland, Finnish and Swedish are official languages. In Canada, English and French are official languages. If I have an sv.php file, its locale information might need to be for Sweden, which uses the kroner currency or for Finland, which uses the euro. By extension, a fr.php file might need to use the Canadian dollar or the euro, depending on whether the locale is Canada or France.

I tried to have locale files with extended names, such as fi_fi.php and fi_sv.php, but Akelos looks for separate controllers.

Has anyone worked out a good method to deal with this problem?
