On Windows XP and Windows 7 number culture fr-CH is : 1'000.00 'as thousand separator and .as decimal
on Windows 8 number culture fr-CH is : 1 000,00 this is wrong.
On Windows Phone 8 (Nokia Numia 920) it is wrong too, calculatior shows 1000,50 insteed of 1000.50
I did mentionate this on french forum since Windows 8 preview !
I suppose that all these forum are "write olny" ! nobody read and take action at Microsoft !?
