Gorm the output of .Debug() for UUID binary(16)

I use MySql binary(16) to store UUID generated from google uuid pkg. When under '.Debug()' mode, like db.Debug().Create()... on the output of SQL statement, some uuid will be output as '', but some uuid will be output as '%5ČA\ufffd@\"\ufffd4\ufffd q! \ufffd' which is invalid UTF-8.
