Ed Berezitsky updated NIFI-5874:
--------------------------------
    Description: 
If there is backslash sequence (like \t, \n, etc) in the input, 
CSVRecordSetWriter transforms them into actual characters (new line, tab, etc) 
in output record.

For example, input record:

 
{code:java}
case,a,a1
tab,=\t=,-
{code}
 

Update Record with `/a1: /a` (just copy value from one field to another)

JsonRecordSetWriter will produce:
{code:java}
[{"case":"tab","a":"=\t=","a1":"=\t="}]{code}
while CSVRecordSetWriter will produce:
{code:java}
case,a,a1
tab,= =,= =
{code}
there is a actual "tab" in between "="
