      Comparing “expected” with “received”, there is really some question mark difference.

      For example, in “expected’, it’s

      "type_decimal_bytes": {"bytes": "\u0007?”}
      

      While in “received”, it’s

      "type_decimal_bytes": {"bytes": "\u0007??"}
      

      The environment I ran the unit tests on uses ANSI_X3.4-1968

      I changed to "en_US.UTF-8" and the unit tests passed.
