@juicifer After much searching, I think the answer is [PICHILEMU](https://en.m.wikipedia.org/wiki/Pichilemu) . It's P (Provincial capital) I (one) on the west side of CHILE (where Pichilemu is) with MU (foreign (Greek) character).
It's also the capital of the province of Cardenal Caro, and is right beside the western border of Chile. However I don't know what "foreign character" is doing in the surface...
