Null character within json

After an hour of googling I am kind of embarrassed to ask this. But are null characters (ascii null or \0) allowed within json? I can find that it's not allowed within json strings but my question is if it is allowed withing the body at all.

So is something like this valid:

{
    "MyKey": "MyValue"\0
}

Where the \0 is an actual null character not an escaped one.

According to JSON specification JSON cannot contain \0, only spaces between tokens:

Insignificant whitespace is allowed before or after any of the six
structural characters.

   ws = *(
           %x20 /              ; Space
           %x09 /              ; Horizontal tab
           %x0A /              ; Line feed or New line
           %x0D )              ; Carriage return
