[LOCALIZATION] How to add my own Culture

@Jamie; Anyway to share the changelist at which this was fixed, if it was? We’re using an older version of Unreal Engine (4.8) and I’d like to integrate this change over since we’re also trying to add support to a language other than the ones supported outside of all.

Otherwise, you’re suggesting replacing the icudt53l folder with the contents from the all folder which would probably work fine. Seeing as these files are usually obtained automatically by the GitDependencies exe, it wouldn’t cause any problem to setup our depot to directly contain the files instead?
