It could be that the 3 characters \xE2, \x88 and \x9E are not valid characters that would fit into the type that you have defined. Check the data in the Excel spreadsheet to make sure it contains only valid characters that correspond to the datatype you are importing into.
How are you uploading the data into the database? Are you converting Excel to CSV or are you using ODBC to perform this operation? It looks like you are using multiset characters. Have you created the database and table using UTF8 characterset?
I have investigated a little more and found that there appears to be a bug with insert statements with a different characterset. Take a look at this link
