Bug#27562: ascii.xml invalid?

Two character mappings were way off (backtick and tilde were "E"
and "Y"!), and three others were slightly rotated.  The first 
would cause collisions, and the latter was probably benign.

Now, assign the character mappings exactly to their normal values.


sql/share/charsets/ascii.xml:
  Change the character mapping for 
   "`" to "`" (was "E") and 
   "[" to "[" (was "\") and 
   "\" to "\" (was "]") and
   "]" to "]" (was "[") and 
   "~" to "~" (was "Y").
