Im working on a shop running on the Venue theme and translated in 3 languages, and noticed that the language "français" (set as default language) has no capital letter in any Language Selector (header, sidebar and footer), therefore breaking consistency with "English" and "Nederlands". Is there a way to fix/customize this through code ? While I am at it, is there a way to put it in language code ("EN", "FR" and "NL") instead ? I guess if the first question finds an answer I would be able to change the language labels to whatever.
My second question is about editing the text "Quantity" on the Product page or in the Cart. I would like to change it to "Box quantity" for example.
Let me know if you need more informations to solve this.
