Ok, thanks for adding the picture. If this has definitively been identified as Romanian, I think that is the best way to deal with the symbols.
I have a suspicion that it's not actually Romanian. Google Translate's "detect language" feature labels it as Croatian, which would certainly fit with the symbols you've indicated. Does the song also have the comma-below letters or the accented vowels found in the Romanian alphabet (and not the Croatian alphabet)? If not I would be increasingly suspicious. Still, if the requestor says it's Romanian, treating it as Romanian is a very reasonable thing to do.
