 ### `time.Time` support
 The default internal output type of MySQL `DATE` and `DATETIME` values is `[]byte` which allows you to scan the value into a `[]byte`, `string` or `sql.RawBytes` variable in your programm.

 Alternatively you can use the [`NullTime`](http://godoc.org/github.com/go-sql-driver/mysql#NullTime) type as the scan destination, which works with both `time.Time` and `string` / `[]byte`.
 
 
+### Unicode support
+Since version 1.1 Go-MySQL-Driver automatically uses the collation `utf8_general_ci` by default. Adding `&charset=utf8` (alias for `SET NAMES utf8`) to the DSN is not necessary anymore in most cases.

 ## Testing / Development
 To run the driver tests you may need to adjust the configuration. See the [Testing Wiki-Page](https://github.com/go-sql-driver/mysql/wiki/Testing "Testing") for details.
