@theadamparker , can you have a look at the mockups at https://undp.github.io/design-system-i18/ to check if all those languages are showing ok, at least from the entirely visual point of view? We would like to validate that generic typography styles applied correctly (font size, line height, letter spacing, ets), then we will involve native speakers.
