Illegal character(s) in message header

Hello All,
      I am facing a Callout exception which says " Illegal character(s) in message header value: 
{"HEADER": {"APPLICATION-ID": "APP-0000010120", "CUST-ID": "P/001N000000p35DTIAY","REQUEST-TYPE": "REQUEST","REQUEST-TIME":"08092016 16:15:11"},"REQUEST": {"03":"PERSONAL LOAN","04":"421000","07":"DIRECT","11":"QA/UAT","21": {"01":"A B C"},"22":"MALE","27":"02091992","29":[ {"01":"RESIDENCE","03":"543543544","04":"Bihupuria","06":"Assam","05":"435435"}],"30":{"01":"YHGPS7560W"},"31":[{"01": "MOBILE","02":"9664561852"}],"36":"456465465464"}}
"

I have set the header if the request as follows:-
httpReq.setHeader('inputJson_',jsonRequestBody); 
In the 'jsonRequestBody', I have set the content that is show above in curly braces. 

Strange thing is that, if I use the same header value through a REST client (Postman), it works fine. From within Apex, I get the above mentioned issue. Can anyone let me know what is wrong here?

Regards,
Gautam.

The issue was with a newline character that I had in my code while forming the request. Removed the newline (\n) character from the Apex code and the request went through fine.

Hello Karthikeyan,
            I have tried by removing '/' and ':' (colon) but it did not help. It still shows the same error.

Hello Gautam, 

Before sending request encode you JSON string using like this.

String myBase64String = EncodingUtil.base64Encode(Blob.valueof(myString));
