I know of no English speaking country that uses the comma this way. But plenty of non English speaking country does it.

England uses the comma this way. I.E. would format it 10,000%.

I think you misread the thread you're responding to.

The OP used a comma as decimal point, not to as a thousands separator. GP likely meant they know of no English speaking country that uses the comma as decimal point. Your example doesn't contradict or add to that.
