It's a real problem for us using Spanish.
We have a page aimed at our national market with prices in the local currency.
We have another almost identical page but with prices in US$ & Euros. I don't want the national market going to the US$ page as we have currency controls & it could cause legal problems.
In the same way I don't want my customers from outside our country seeing prices in the local currency because they are meaningless to them due to different official & black market exchange rates.
I have marked the HTML as "Espaņol country" on the national page & Espaņol Spain" on the other.
