It appears to be at the beginning of your file so you could remove it by deleting the first few characters and retyping them and then re-uploading the file.

Path '', line 1, position 2. This type of escaped strings are usually generated when a string that was already a json string, its serialized again or even more times. So, to remove them correctly is not enough to replace them by empty. Correct the type you want the json to be converted. I modified your json a little as follows and it worked. The problem occurs when valid double quotes are used within the answer.
It frustrated me too until I found a simple solution:. Learn more. Json: how to properly strip the escape characters with json. Asked 6 years, 11 months ago.
A JSON number numeral is represented in decimal notation, possibly signed and possibly including a decimal exponent. An object property is often called a field. An object property name-value pair is often called an object member. Order is not significant among object members.
A JSON field name can be empty "". Each field name in a given JSON object is not necessarily unique; the same field name may be repeated.
Array element order is significant.
Most of the fields have string values. Fields PONumber and zipCode have numeric values: and Field Shipping Instructions has an object as value. This object has three members, with fields nameAddressand Phone. Field name has a string value "Alexis Bull". Fields Address and Phone each have an object value. The value of field Address is an object with fields streetcitystatezipCodeand country. Field zipCode has a numeric value; the others have string values. Field Phone has an array as value.
This array has two elements, each of which represents an object literal. Each of these objects has two members: fields type and number and their values. Field LineItems has an array as value. This array has two elements, each of which is an object. Each of these objects has three members, with fields ItemNumberPartand Quantity. Fields ItemNumber and Quantity have numeric values.The square brackets indicate that it's an array, so your example there is an array containing 2 strings.
As you can see, I'm using 2 functions. When I apply the code you provided it doesn't work. Any ideas? You need to parse the JSON stored in the local storage before outputting each item from the array to the history element. I resolved this problem by moving the History Information Array outside of the clearWatch function. I will ask one more question. Is there anyway to append a localStorage. And if so, how could I incorporate it within my existing code?

I was investigating various problems with JSON parsing in fluent-bit. There's a lot of other Issues about this, but I felt it'd be useful to get a minimal reproduction, against latest master, and with all the issues I found in one place. Issues I believe are related, at least based on a quick scan:,, As far as I can tell, there's no way currently to configure fluent-bit to correctly parse a JSON string value.
This will work for everything except strings that contain literal backslashes. See below for detail. Alternately, if you want to parse nested JSON, you should apply the json decoder only. All the following is based on commit 00ddwhich is master at time of writing. Here is my config file. I am using the tail input and file output for testing purposes and to keep the tests free of other distractions.
The crux of the whole problem is with how fluent-bit parses JSON values that contain strings. The string tokens returned by jsmn point to the section of the buffer that is between the opening and closing quotes of the string. Note how this substring still contains the escaped newline as a backslash then an n, not as an unescaped actual newline character.
However, the documentation somewhat obliquely indicates that you are meant to use a decoder to rectify this siutation.
If you know in advance exactly what fields you need to apply this to, then we can attempt to use decoders to improve this. However, I'd like to point out that at this point we already are no longer able to process arbitrary JSON objects, since there's no way to apply a decoder to "all string fields" without hard-coding that set of fields in your config file. Any other escaped characters eg.
In addition, this decoder has a somewhat subtle bug. The code loops through each character, checking if it is a backslash and the next char is not in the list of chars that would make it a JSON escape. The next character, of course, is another backslash.

This also gets interpreted as an escape. Turning this minor buffer overflow into a segfault or further business is left as an exercise for the reader. Since fluent-bit keeps string lengths alongside all its strings, the fact that we have an extra NUL terminator doesn't seem to affect things too much.
It shows up in the output, eg. For fields which contain strings intended to be parsed as JSON, eg. One important aspect of this decoder and not documented anywhere as far as I can tell is that it first does a escaped decode on the string before attempting to parse it. However, note that as discussed above, the escaped decoder does not correctly parse unicode escapes. But there are valid albeit pathological JSON documents which will therefore fail to parse, as any character may be replaced with a unicode-escaped version even if it's otherwise valid.
The code is also not capable of outputting non-BMP unicode characters. This could arguably be considered a parsing bug, not an encoding bug. Surrogate pairs are not valid in utf-8 strings, and when these characters are attempted to be encoded, the implementation arguably correctly reports [pack] invalid UTF-8 bytes, skipping and drops those characters. After that, things get trickier. As part of this change, the json decoder should also use this decoding step instead of escapedso it can correctly interpret unicode-escaped characters.
However, none of this deals with the case where the user cannot hard-code in their config file the full list of fields that need to be decoded.US: 1 Remember Me? Forum Ext JS 2.
