Parsing special characters in short description field of the Incident table

[soibam_ana_sing]

We are integrating SNOW with a third party software. We would like to update "short description" field in Incident table with the messages comming from third party software. The whole message is made of special characeters/latters/digits ect  and throw error " Failed to decode message" with SNOW REST APIs. 

In case of manually updating description field, it works fine but REST APIs throw error message.

Status: 400 Headers: {'Set-Cookie': 'JSESSIONID=313682F13FD6C48FCFE56C38C70A7C2D; Path=/; HttpOnly;Secure, glide_user=; Max-Age=0; Expires=Thu, 01-Jan-1970 00:00:10 GMT; Path=/; HttpOnly;Secure, glide_user_session=; Max-Age=0; Expires=Thu, 01-Jan-1970 00:00:10 GMT; Path=/; HttpOnly;Secure, glide_user_route=glide.af0c44639e8846b5475107a73fa45221; Max-Age=2147483647; Expires=Sat, 30-Aug-2087 14:20:43 GMT; Path=/; HttpOnly;Secure, glide_session_store=D8A82298DB5333009798AF264896197D; Max-Age=1800; Expires=Mon, 12-Aug-2019 11:36:36 GMT; Path=/; HttpOnly;Secure, BIGipServerpool_dev85551=578902026.54336.0000; path=/; Httponly; Secure', 'Content-Encoding': 'gzip', 'X-Is-Logged-In': 'true', 'X-Transaction-ID': '10a82298db53', 'Pragma': 'no-store,no-cache', 'Cache-control': 'no-cache,no-store,must-revalidate,max-age=-1', 'Expires': '0', 'Content-Type': 'application/json;charset=UTF-8', 'Transfer-Encoding': 'chunked', 'Date': 'Mon, 12 Aug 2019 11:06:36 GMT', 'X-Cnection': 'close', 'Server': 'ServiceNow', 'Strict-Transport-Security': 'max-age=63072000; includeSubDomains'} Error Response: {'error': {'detail': 'Cannot decode: java.io.StringReader@ffbc12', 'message': 'Exception while reading request'}, 'status': 'failure'}

It is one-way  communication from third party software to SNOW instance. is there python package available for String handling functions "GlideStringUtil". Looks it is not availble  in servicenow packages 

 pip install servicenow
