字符串反序列化时出现bug

[bitterzzZZ]

反序列化时，对字符串中的反斜杠 \ 判定为后一个字符的转义，从而反序列化出错
测试代码如下

char a = 0x5c;
HashMap<Object, Object> hashMap = new HashMap<>();
hashMap.put("1",a);

String string = JSON.toJSONString(hashMap);
System.out.println(string);
JSON.parse(string);

输出结果和报错信息如下

{"1":"\"}
Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 9
	at com.alibaba.fastjson2.JSONReaderUTF16.readString(JSONReaderUTF16.java:1211)
	at com.alibaba.fastjson2.reader.ObjectReaderImplMap.readObject(ObjectReaderImplMap.java:390)
	at com.alibaba.fastjson2.reader.ObjectReaderImplObject.readObject(ObjectReaderImplObject.java:21)
	at com.alibaba.fastjson2.JSON.parse(JSON.java:22)
	at com.bitterz.test.main(test.java:35)

hashmap中放入其它键值对时报错不同

ArrayList<Object> list = new ArrayList<>();
list.add("123");
list.add("123");
char a = 0x5c;
HashMap<Object, Object> hashMap = new HashMap<>();
hashMap.put("1",a);
hashMap.put(list, 1);

String string = JSON.toJSONString(hashMap);
System.out.println(string);
JSON.parse(string);

输出结果和报错内容如下

{"1":"\","[123, 123]":1}
Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 24
	at com.alibaba.fastjson2.JSONReaderUTF16.readFieldName(JSONReaderUTF16.java:510)
	at com.alibaba.fastjson2.reader.ObjectReaderImplMap.readObject(ObjectReaderImplMap.java:352)
	at com.alibaba.fastjson2.reader.ObjectReaderImplObject.readObject(ObjectReaderImplObject.java:21)
	at com.alibaba.fastjson2.JSON.parse(JSON.java:22)
	at com.bitterz.test.main(test.java:25)

处理Character类型的特殊字符时结果不对，已经修复。
