Localization is a hard problem. Too many factors to consider. If you are building a MVP, I would advise not spending too much time on it. You can certainly leave some placeholders in the application if it fits but building a full blown localized product is 2-3 times harder (in my experience). You also said "which hopefully will have global applicativity." So you are not quite there yet where you know for sure that it will be global. What if it doesn't or takes you a while to first validate the market in general ? My advice: Build the MVP quickly, validate the product and then think about localizing if you get enough traction.
