Comment 30 for bug 1576411

I wonder if my `locales-launch` remote part can workaround this issue at the snap end?:

Also according to the discussion at https://forum.snapcraft.io/t/lack-of-compiled-locales-breaks-gettext-based-localisation/3758 , can't we just simply put a copy of compiled data of all reasonable locales into the core snap?
