1.1.7 encode crash

[shy3533]

{"code":0, "data":{"text":"�ɪV�+|�!��^r�Ǘ�\u0026\b\u0005˵U۳.\f���","texts":[{"source":"v1Vg24nSA19fK0b67rX1YGToxXbv8mz52VNfFus3TDU7A=","target":"�ɪV�+|�!��^r�Ǘ�\u0026\b\u0005˵U۳.\f���"}]}}

when i decode this string to map[string]interface{}, it work fine. but encode to json string, the encoder use all of my memory, the app crashed

I don't understand what you are saying.

Can you please attach a reproducer that I can run with "go run" or "go test". This should clearly say what is expected to happen, and I run it and see what happens.

I believe this is the same issue as #317 -- the problem is the Unicode replacement character \ufffd.
