We’ve developed a multilingual site using Pimcore5, and it’s been a pleasant experience overall. But now we need to add english versions for each country of the site (the site is available in the Scandinavian countries), so apart from sv_SE, nb_NO, fi_FI and da_DK, we would need en_SE, en_NO, en_FI and en_DK. Yep, per country, not one english version of the site, but four.
Those however are not existing locales. Any suggestions on how to set this up?
