Testing a locale with space as thousands separator and dot as decimal point

MacOS system settings allow the user to select one of a number of number formats. My app behaves differently depending on the format (taken from the system Locale), so I need to test every combination.

Thus far I have been successful at creating Locale objects with various identifiers that map to the different formats, like:

let westEuropeanLocale = Locale(identifier: "en_DE")

However, I can't find a locale that maps to using . as a decimal point, and space as a thousands separator, even though it's a standard option (3rd in this list):

Any suggestions on how to create a test for this number format?
