Format Text node inserts blank spaces when converting int, no thanks!

When converting large int, like 1000000 FormatText will insert blank spaces every 3 characters and output 1 000 000.
Bug or feature?

Like the “,” in the American Number formating (1,000,000.000)
The EU formating is with Spaces (1 000 000,000)

Is there a way tho remove it with some secret syntax? Documentation for that node is blank.
