Description:
------------
Apparently it's impossible to decode strings with escaped "escape" character: 

\\

this should work however, as it's written in the json specs on http://json.org/

Test script:
---------------
<?php

var_dump(json_decode('["\\"]', true));

?>

Expected result:
----------------
array(1) {
  [0]=>
  string(1) "\"
}

Actual result:
--------------
NULL

You are confusing PHP escapes and json escapes.

Watch:

php > $str = '["\\"]';
php > echo $str;
["\"]

That's obviously not valid json.  What you actually want:


php > $str = '["\\\\"]';
php > echo $str;
["\\"]
php > var_dump(json_decode($str));
array(1) {
  [0]=>
  string(1) "\"
}

Works fine.  No bug here.
