One of my configuration, which is actually a sql query, contains both single and double quote chars. So, the usually preferred way to do single quote wrapping double quotes (or the other way round) cannot be used. I need to explicitly escape with "" but that kind of escape has the following defect:

I do this

> mutate {  
> add\_field =\> { "foo" =\> 'string with " and ' chars' }  
> add\_field =\> { "bar" =\> "string with " and ' chars" }  
> }

And, I output the result to file with json\_lines codec.

**Expected result:**

`..."foo":"string with \" and ' chars","bar":"string with \" and ' chars" ...`

**Actual result:**

`... "foo":"string with \" and \' chars","bar":"string with \\" and ' chars"...`
