mysql_priv.h:
  define over-ridden append_escaped to take arguments from 'create_where_from_key' method in federated handler 
ha_federated.cc:
  implemented "create_where_from_key" to deal properly with two-byte prefix and multi keys. Initial testing shows it works, but I still need to move quoting to field class and also look at changes per Segei's suggestions.
