> @yl-yue Only RpcException can be thrown in the filter. Please provide an
example of garbled characters. I think the second problem needs to be fixed.
filter throw exception:
```java
@Activate(group = CommonConstants.PROVIDER)
public class TokenFilter implements Filter {
@Override
public Result invoke(Invoker<?> invoker, Invocation inv) {
throw new RpcException("错误的token");
}
}
```
result:
```json
{
"error": "13 INTERNAL: Exception in invoker chain :???token"
}
```
Whether a Filter throw Exception or another throw exception, any message
containing Chinese will be interpreted as garbled(`?`)
