      Description

      Hive supports CAST('1' as BINARY). Result is 0x31 (can be tested with

      SELECT HEX(CAST('1' as BINARY));

      . If I'm not mistaken, the CAST result is the UTF-8 encoding of the input string.
      CALCITE 1.11 throws AssertionException during compilation for such an expression:
