Added MY_CS_NONASCII marker for character sets that are not compatible with latin1 for characters 0x00-0x7f
This allows us to skip and speed up some very common character converts that MySQL is doing when sending data to the client
and this gives us a nice speed increase for most queries that uses only characters in the range 0x00-0x7f.
This code is based on Alexander Barkov's code that he has done in MySQL 6.0
