It's difficult to encode the json with special characters such as '"', '>'...
encoding and unicoding these characters will change the length of json message,
it's a pain to get bytes contains these characters from json.
This patch allows to read the bytes contains special character outside the json.
for example:
{"container":"c5f67934326d2ecef59fee62148bc9237e2481cd803cc0760a6406da15f4ee60","file":"/tmp/aaa"}sssssss
