    Description

      Reproduced on 10.11.19 (debug build):

      SELECT JSON_CONTAINS('{"k":"\u0041"}', '{"k":"A"}'),   -- 0
      		 
             JSON_EQUALS('"\u0041"', '"A"'),                 -- 0
      		 
             JSON_OVERLAPS('["\u0041"]', '["A"]'),           -- 0
      		 
             JSON_UNQUOTE('"\u0041"');                       -- A

      The same string written as an escape and written directly compare as different, although JSON_UNQUOTE on the same server decodes the escape to A. Expected: 1 / 1 / 1.
