[RFC][PATCH][BZ 20756] Locales: Use Unicode wise thousands separator

[keld@keldix.com]

I agree to change space to something else. Given the problems mentioned below with fonts,
maybe a good way forward is to use NBSP, which should be   available in all fonts,
and also is available in olden 8-bit charsets, that are still in use.

Best regards
Keld
