             Summary: Config to support [?json_string] globally 
                 Key: FREEMARKER-231
                 URL: https://issues.apache.org/jira/browse/FREEMARKER-231
             Project: Apache Freemarker
          Issue Type: Bug
    Affects Versions: 2.3.30
            Reporter: Lahiru Madushanka


Hi Devs,

I'm creating this issue on behalf of the WSO2 Micro Integrator team. We are 
using Freemarker in our product to transform user payloads and are quite happy 
with the functionalities and ease of use. 

Recently, we got an issue from our customer saying the String values are 
getting escaped in a JSON payload

25.09\t& get changed to 25.09[0x09]&

Sample configuration

 
{code:java}
"ResponsePayload": { "result": { "Table": { "FAULT_DESC": "${ctx.CEPFaultDesc}" 
} } 
{code}
 
We later inject the ctx.CEPFaultDesc value to freemarker. 
 
Upon doing some research, we asked the customer to use the following config 
with ?json_string, which resolved the issue
 
{code:java}
"ResponsePayload": { "result": { "Table": { "FAULT_DESC": 
"${ctx.CEPFaultDesc?json_string}" } }{code}
 
 
But, the problem is we feel like it's wrong to escape the string values. We are 
creating this issue to check if there's a way to apply this config change 
globally (not in individual fields). If not, will it be considered in a future 
release? 
 
We are using version 2.3.30
 
Thanks in advance.
