- 版本信息：[e.g.：Fastjson2 2.0.40]

### 重现步骤
```java

JSONObject jsonObject = JSON.parseObject(text);
System.out.println(jsonObject.toJSONString());
// {"message":"\b\u0001\u0012\u00072041718 ���0*\u001b\n\u0004Tags\u0012\u0013{\"1\":{\"isTop\":\"0\"}}"}

```

### 期待的正确结果
按照原有格式解析输出

Start with the supplied Java reproducer and trace JSON.parseObject(text) through the string parsing and serialization path. Compare the parsed and re-serialized message against the original escaped content; done means the Protobuf-encoded characters are preserved without replacement characters or altered output.

Written by the indexing model from the issue text.
