Robin Lutz commented on NIFI-3303:
----------------------------------
This Bug is still present in 1.11.2 .
I attached a small example how to work around it. [^ReplaceText_Bug.xml]
Besically what you need to do is escape the Text twice:
${'$1':escapeJson():escapeJson()} and the processor will unescape it once back.
The issue might be related to this issue:
https://issues.apache.org/jira/browse/NIFI-3837 . It helped me come up with a
work around.

>
> I have some problems while using excapeJson and unescapeJson in ReplaceText
> processor.
> When I give a string: He didn’t say, “Stop”! to ReplaceText as input,and
> configure ReplaceText like: attachment config.png
> The output of ReplaceText is same with the input: He didn’t say, “Stop!”
> ,nothing changed.
> As described in NiFI Documentation the output should be: He didn’t say,
> \"Stop!\”.Did I miss something?
> Also there are problems with unescapeJson.If input is: He didn’t say,
> \”Sto\\\"p!\”,the return string will be: He didn’t say, ”Sto"p!”.
> My dataflow:(GetFile just read a file with a string as content.)
> dataflow.png
> Thanks.
