"\0" is invalid JSON

[akvadrako]

According the JSON specification, "\0" is not a valid JSON string and must be encoded with four hexadecimal bytes. It's not just a theoretical problem - some python JSON parsers do not accept it.

The BrowserCompatible mode does handle this correctly, but I don't want to escape forward slashes.

I recommend the following unit test:

public class FastJsonTest {
    @Test
    public void testEncodeNulByte() throws Exception {
        String json = JSON.toJSONString("\0");
        assertEquals("\"\\u0000\"", json);
    }
}

Hi. This is quite important to us. I have tried to look at making a patch myself, but this code is fairly complex and I don't want to make a over-reaching change without knowing it would be accepted.

What I don't understand is why the BrowserCompatible code path is so different from the other code path.
