serializeJson not cleaning most of the first 31 characters in the ASCII table.


Problem Description: Invalid JSON data is being created from data extacted from MSSQL tables. chr(1) to chr(7) + chr(11) + chr(14) to chr(31) - Possibly others??

Steps to Reproduce:
See attachment
<!--- chr(1) to chr(7) + chr(11) + chr(14) to chr(31) --->
<cfset char_val = chr(1) >

<cfset tblTemp = queryNew("character", "VarChar") >

<cfset QueryAddRow(tblTemp) >
<cfset querySetCell(tblTemp, "character", "ascii character after here.. " , 1) >

<cfquery dbtype="query" name="ascii_data" >
select [character] + '#char_val#' + ' End' as [character]
from tblTemp

<cfset jsonData = serializeJSON(ascii_data) >

<cfcontent type="text/html; charset=utf-8" />


<!doctype html>
<meta charset="utf-8" />



JSON Data:


View the JavaScript Console:

<script type="text/javascript">

var sJSON = JSON.parse("#JsStringFormat(jsonData)#");




Actual Result: Invalid JSON (parsererror SyntaxError: JSON.parse: bad control character in string literal)

Expected Result: Valid JSON

Any Workarounds: Loop the data to clean using a udf function. It would be better if this was dealt with once at the serializeJson function.

    Unicode characters
    8232 - Line Separator
    8233 - Paragraph Separator
    Break JavaScript code and not the JSON parsing.

    Ben Nadel has just blogged about this issue!
    You will see that there are two further ASCII characters that need dealing with.
    8232 - Line Separator
    8233 - Paragraph Separator

    Bug was discovered from data saved to MSSQL 2008 database Generally SQL string data from nvarchar tables. Characters probably as a result of users copying and pasting data from other systems / PC's / MAC's etc.
