On this previous topic [https://discuss.elastic.co/t/logstash-http-poller-body-escape-double-and-single-quotation-marks/282039/2?u=cad](https://discuss.elastic.co/t/logstash-http-poller-body-escape-double-and-single-quotation-marks/282039/2) someone suggest to use unicode. It's on a different plugin but you should give a try. The unicode for quotes is `\u0022`

Cad.
