Tanks, that did the trick:
data = []
data.append(self.marca.GetLineText(0))#.encode('utf-8'))
sql = "INSERT INTO Marca (marca) VALUES (%s);"
cur.execute(sql, data)

It seems that just by sending the data in a list fixed the problem
though adding the encode doesn't harm either ...
I'll have to make a looot of changes.
by the way, does sending the data as a list prevent SQL injection?
I haven't worried for that yet.
