I found 12 thousand-separators and they are all in the BMP.
It seems even Klingon's thousand separator is in the BMP, even though
the digits are not.

Yes, because the thousand-separator comes from the OS in system code
The UTF-16 version of the RTL can query under Windows the GetLocalInfoW
instead of GetLocaleInfoA.

When someone changes the DefaultSystemCodepage he has to set the format
settings himself. If this is CP_UTF8, then GetLocalInfoW can be used.
