* ruby -v: trunk
* Backport: 2.0.0: DONE, 2.1: DONE
----------------------------------------
Directly coded invalid char causes `SyntaxError`, but not in `eval`.
無効な文字を直接書いたときには`SyntaxError`になりますが、`eval`の中ではなりません。

~~~
$ ruby -e $'\x01'
-e:1: Invalid char `\x01' in expression
bash: exit 1
~~~

~~~
$ ruby -e 'p eval("\x01")'
nil
bash: exit 1
~~~
