One more diff between MySQL and Flink behavior, however this I'm not sure
need to fix since at least from my point of view MySQL's behavior is
questionable
MySQL
```sql
SELECT
JSON_UNQUOTE('"\\u0022\\u005c\\u005c\\u0075\\u0030\\u0030\\u0061\\u0061\\u0022"');
SELECT
JSON_UNQUOTE(JSON_UNQUOTE('"\\u0022\\u005c\\u005c\\u0075\\u0030\\u0030\\u0061\\u0061\\u0022"'));
```
returns
```
"\\u00aa"
\u00aa
```
Flink
```sql
SELECT
JSON_UNQUOTE('"\u0022\u005c\u005c\u0075\u0030\u0030\u0061\u0061\u0022"');
SELECT
JSON_UNQUOTE(JSON_UNQUOTE('"\u0022\u005c\u005c\u0075\u0030\u0030\u0061\u0061\u0022"'));
```
returns
```
"\\u00aa"
