I may see the issue: the textbox is likely configured to display the English strings right next to the dots, which somehow break every other language. And also the textboxes are way to tight, and makes wraping almost inevitable. (Like the in French.) One potential fix for now could be to modify the size of the renderd string using Unity's Rich Text function, on a string-to-string bases.

This is also the case for Japanese and Korean
