    languages: Use a more broadly compatible locale codeset suffix
    
    At least OpenBSD's libc doesn't accept 'utf8' as a locale codeset
    suffix but does accept 'UTF-8'. Since GNU libc accepts both suffixes
    let's use the one which works on a broader set of systems.
    
    Thanks to Stefan Sperling and Antoine Jacoutot.
