Right now the plan is to avoid implementing locales as much as possible. They cause hard to debug errors (e.g. https://sam-cooper.medium.com/the-country-that-broke-kotlin-84bdd0afb237) and generally hurt performance as a piece of global state functions have to check. 

I think the config should probably be switched to UTF-8 by default for linux.
