    Description

      Test:

      create table t1 (c varchar(30) character set utf8, t text character set utf8, unique (c(2)), unique (t(3))) engine=myisam;
      insert t1 values ('cccc', 'tttt'),
        (0xD0B1212223D0B1D0B1D0B1D0B1D0B1, 0xD0B1D0B1212223D0B1D0B1D0B1D0B1),
        (0xD0B1222123D0B1D0B1D0B1D0B1D0B1, 0xD0B1D0B1222123D0B1D0B1D0B1D0B1);
       
        select c from t1 where c=0xD0B1212223D0B1D0B1D0B1D0B1D0B1;
       
      create or replace view v1 as select c from t1 where c=0xD0B1212223D0B1D0B1D0B1D0B1D0B1;
      select * from v1;
       
      drop view v1;
      drop table t1;
      

      Expected result:
      Result of

       select c from t1 where c=0xD0B1212223D0B1D0B1D0B1D0B1D0B1; 

      and

       select * from v1; 

      must be the same, but

       select * from v1;

      gives an empty result
