Hey @Jhondy -
This one felt familiar to me, and I found the thread this reminded me of [see @amits comment at the bottom]:
It looks like we have seen something similar before with hebrew characters which is just related to how excel on windows handles this character encoding. Amit was able to get around this by save-as-ing the file to the utf-8 with BOM encoding format.
I would be curious to see if this fixes your issue-
Pete
