Spanish .csv Import accents and tildes (á & ñ)

When trying to import vocabular using .csv import into the site, although I am able to type the accents and tildes into the .csv file (using Excel), when I import, the vocabulary on the site does not “take” the accents and tildes. If I would like to import a large amount of Spanish vocabulary using .csv files, with many accents and tildes, how do the site administrators recommend I accomplish this?

Are you sure that accents are preserved in the CSV file before you import it? Can you please send us your file to support(at) so that we can take a look? Thanks!

I just sent the file. Thank you!
