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

For example, in “expected’, it’s
{code:java}
"type_decimal_bytes": {"bytes": "\u0007?”}
{code}

While in “received”, it’s 
{code:java}
"type_decimal_bytes": {"bytes": "\u0007??"}
{code}

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.
