Hi guys,
I think logstash quote escaping has a bug.
I do this
> mutate {
> add\_field =\> { "foo" =\> 'string with " and ' chars' }
> add\_field =\> { "bar" =\> "string with " and ' chars" }
> }
I output the result to file with `json_lines` codec. I expect this:
> "foo":"string with " and ' chars","bar":"string with " and ' chars"
But, the actual output is this
> "foo":"string with " and \' chars","bar":"string with \" and ' chars"

It's quote silly that backlash escape character becomes part of the string! It is a catch22!

Please don't post multiple topics on the same problem, see [Quote escaping bug in logstash configs](https://discuss.elastic.co/t/escape-quotes-in-logstash-config/60112)
