Despite spending an hour searching online, I feel a bit hesitant to ask this question. Can null characters (ascii null or \0) be used within JSON? I know they are not allowed within JSON strings, but my query is whether they can be included in the body at all.
So, is something like this considered valid:
{
"MyKey": "MyValue"\0
}
Where the \0 represents an actual null character and not an escaped one?
As stipulated by the JSON specification, JSON does not allow the inclusion of \0 character; instead, only spaces are permissible between tokens:
Insignificant whitespace can exist before or after any of the six structural characters.
ws = *(
%x20 / ; Space
%x09 / ; Horizontal tab
%x0A / ; Line feed or New line
%x0D ) ; Carriage return
