OK, the rule sheet says: "When travel originates in a country for which a specific local currency fares is published and the ticket is sold in another country, the fare will be that published for the country of origin converted to the currency of the country of sale at the bank selling rate."

So what happens in a country where there is a specific local fare, but it's in dollars or some other currency? I can't remember this possibility ever having come up, but it must exist. And is there any significance to the fact that the phrase 'a specific local currency fareS' is in the plural (despite the singular 'a')?
