Working in Windows I found that there are two magic localizations: non localized is a default failsafe that is a copy of EN-US. The other fun one is “pseudo-loc” which is used in testing; it replaces letters with similar ones that have accents or diacritics to detect hard coded English strings. I wonder if the EN-US keyboard is actually a fall-through to the non-localized version when the localized keyboard fails to load.
