Send From File truncates messages with special Characters

When using Send From File feature, sent messages are truncated on the first special character of the loaded CSV. I´ve created a CSV file including common Spanish characters including accented vocals. File uploads OK but, when I check the MySQL playsms_featureSendfromfile table in database playsms you can see that the loaded message is truncated at the first special character. An UTF-8 or some sort of coding must be inserted some place but I’m not familiar with the programming.
Any help will be appreciated.
Thanks in advance.
