Description:
When creating a connection and table with charset=GB18030 the inserted values will sometimes be incorrect.

Behavior indicates that encoding is not being properly handled.
The result of executing _encoding.GetBytes() in MySqlPacket.WriteStringNoNull() is not always correct when using said charset. 

How to repeat:
The bug is intermittent and is very hard to reproduce. Multiple executions of the same code is required.

Try opening a connection with charset GB18030 and to create a table with same charset. Upon inserting values to the table the error may occur.
