[gtksourceview/wip/encodings: 6/6] Ensure that UTF-8 and CURRENT are present in the candidate encodings

    Ensure that UTF-8 and CURRENT are present in the candidate encodings
    
    In the gedit translations, CURRENT was sometimes translated (and there
    is a translator comment to explain that it should not be translated...).
    So it's better to ensure that UTF-8 and CURRENT are present, just in
    case.
