### 请描述您的问题

```json
{
"property": {
"session": "client-sdkA",
"subject": "macs/ods/tagschema/unit01"
},
"message": {
"namespace": "HH800",
"values": [
{
"id": "AMACC1A8CNDWTRTEM.AM",
"type": "BYTE",
"description": "空冷1\8列凝结水温度（选取）"
},
{
"id": "AMACC1A8CNDWTRTEMXX.AM",
"type": "BYTE",
"description": "空冷1\8列凝结水温度选小"
}
]
}
}
```
通讯字符串对象如上，代码处理如下：
```java
public class JSONTest {
@Data
public static class OdsData{
private OdsDataProperty property;
private OdsDataMessage message;
@Data
public static class OdsDataProperty{
private String session;
private String subject;
}
@Data
public static class OdsDataMessage{
private String namespace;
private List values;
@Data
public static class OdsDataValue{
private String id;
private String type;
private String description;
}
}
}
/**

JSONReader.Feature[] FASTJSON_DEFAULT_READER_FEATURES = {JSONReader.Feature.SupportSmartMatch, JSONReader.Feature.SupportArrayToBean, JSONReader.Feature.UseNativeObject, JSONReader.Feature.SupportClassForName,JSONReader.Feature.IgnoreSetNullValue,JSONReader.Feature.AllowUnQuotedFieldNames,JSONReader.Feature.IgnoreCheckClose,JSONReader.Feature.IgnoreAutoTypeNotMatch };

public static void main(String[] args) throws Exception {

OdsData obj2 = JSONObject.parseObject(jsonStri, OdsData.class,FASTJSON_DEFAULT_READER_FEATURES);
System.out.println(obj2);
}

}
```
期望可以正常转换

Start with the JSONObject.parseObject call and the JSONReader.Feature configuration shown, then verify how the parser handles the \8 sequence. The issue names no repository files or tests; done means the expected behavior for this non-standard escape is agreed and covered by a regression test.
