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.
