the argentinian currency is wrong by default, it's "Pesos argentins" and it should be "Pesos argentinos" (notice the missing 'o') It's not difficult to change at all, but it'd be great if it's corrected in the dolibarr distribution.
BTW, where are the string in the dictionaries stored? Should the Z-6PO correct them and commit the changes too? The translators doc just talk about the langs folder, and the dicts are not there (not the currencies at least)
