I did not know that. Very interesting, thanks. Not so fun fact: Switzerland, although German speaking, does not use the comma. Also their keyboard Layout is all over the place with German French and Italian influences.

German: I hate that we use comma as a decimal separator. Makes working with international documents a hassle, my numpad on pc makes a comma so I cannot even type a date…we like to complain about us imperial units as much as anyone but our comma is almost as stupid!
