```go
import "github.com/bytedance/sonic/decoder"
var data interface{}
dc := decoder.NewDecoder("[[[}]]")
if err := dc.Decode(&data); err != nil {
if e, ok := err.(decoder.SyntaxError); ok {
/*Syntax error at index 3: invalid char
[[[}]]
...^..
*/
print(e.Description())
/*"Syntax error at index 3: invalid char\n\n\t[[[}]]\n\t...^..\n"*/
println(fmt.Sprintf("%q", self.Description()))
}
/*Decode: Syntax error at index 3: invalid char*/
t.Fatalf("Decode: %v", err)
}
```
