json_encode returns empty string if logged object property is a Resource or has some "weird" chars.

[szaqal83]

I'm trying to log a object representing a AD user (using Adldap2 library) and x-chromelogger-data header contains empty string. After some digging I've found (I think) that these properties are causing problems for json_encode:

object(Adldap\Connections\Ldap)#5 (4) { ["connection":protected]=> resource(1) of type (ldap link) ["bound":protected]=> bool(true) ["useSSL":protected]=> bool(false) ["useTLS":protected]=> bool(true) }

["objectguid"]=> array(1) { [0]=> string(16) "4�ǘ=��F�Q9�����" }

["objectsid"]=> array(1) { [0]=> string(28) "����9aS��g^��p�f3 " }

whole object looks like this:

object(Adldap\Models\User)#9 (9) { ["exists"]=> bool(true) ["dateFormat"]=> string(11) "Y-m-d H:i:s" ["dn":protected]=> string(58) "CN=Lena Oronowicz,OU=Tarnobrzeg,OU=Pracownicy,DC=PUW,DC=RZ"

checking encoding of 'objectguid' and 'objectsid' using mb_detect_encoding() returns UTF-8 so it looks ok I think. I've added some extra code inside _convert function of ChromePHP to bypass those props and Object showed inside Firefox console.

Encoding object through:

base64_encode(utf8_encode(json_encode($object)))

results non empty string so I think that there is something wrong with the _convert function.
