Differences in International Versions?

It has been an incredible experience meeting people from all over the world that loved Arcane and CaitVi! Honestly didn't realize the global impact until recently. Now I'm thinking back at the "disappearing lesbian super power" that Caitlyn and Vi had in the Chinese version. And it makes me wonder what are some other difference between the North American versions and International versions? Are there any colloquial difference that only made sense in English but not Spanish? What are the different voice actress that brought these characters to life in other languages?
