we are using json php with codeigniter with a webservice and the problem its the & character

this is the json that we are sending to the server

Code:

'data'=>'{
  "rep_front" : 1,
  "rep_content" : 0,
  "meetingUID" : "meeting_51912eb04eb45",
  "projectUID" : "project_51912b6023998",
  "rep_sorting" : 1,
  "rep_images" : 1,
  "footer_text" : "Footer text test...\"",
  "header_text" : "Teste header\" roof & window"
}');

at the server iam doing json_decode

Code:

$j = json_decode($json,true);

i have tried

Code:

$result = utf8_encode($json); // before json_decode

but its not working
