If you want to use   getJSON   you can add the following before the call      ajaxSetup       scriptCharset   utf-8       contentType   application json  charset utf-8        You can use the charset you want instead of utf-8   The options are explained here   contentType   When sending data to the server  use this content-type  Default is application x-www-form-urlencoded  which is fine for most cases   scriptCharset   Only for requests with jsonp or script dataType and GET type  Forces the request to be interpreted as a certain charset  Only needed for charset differences between the remote and local content   You may need one or both

I think that you ll probably have to use   ajax   if you want to change the encoding  see the contentType param below  the success and error callbacks assume you have  lt div id  success  gt  lt  div gt  and  lt div id  error  gt  lt  div gt  in the html      ajax       type   POST       url   SomePage aspx GetSomeObjects       contentType   application json  charset utf-8       dataType   json       data    id       someId             success  function json                success   html  json length     json length           itemAddCallback json              error  function  xhr  textStatus  errorThrown                error   html xhr responseText               I actually just had to do this about an hour ago  what a coincidence

You need to analyze the JSON calls using Wireshark  so you will see if you include the charset in the formation of the JSON page or not  for example    If the page is simple if text   html    0000  48 54 54 50 2f 31 2e 31  20 32 30 30 20 4f 4b 0d   HTTP 1 1  200 OK  0010  0a 43 6f 6e 74 65 6e 74  2d 54 79 70 65 3a 20 74    Content -Type  t 0020  65 78 74 2f 68 74 6d 6c  0d 0a 43 61 63 68 65 2d   ext html   Cache- 0030  43 6f 6e 74 72 6f 6c 3a  20 6e 6f 2d 63 61 63 68   Control   no-cach    If the page is of the type including custom JSON with MIME  charset   ISO-8859-1     0000  48 54 54 50 2f 31 2e 31  20 32 30 30 20 4f 4b 0d   HTTP 1 1  200 OK  0010  0a 43 61 63 68 65 2d 43  6f 6e 74 72 6f 6c 3a 20    Cache-C ontrol   0020  6e 6f 2d 63 61 63 68 65  0d 0a 43 6f 6e 74 65 6e   no-cache   Conten 0030  74 2d 54 79 70 65 3a 20  74 65 78 74 2f 68 74 6d   t-Type   text htm 0040  6c 3b 20 63 68 61 72 73  65 74 3d 49 53 4f 2d 38   l  chars et ISO-8 0050  38 35 39 2d 31 0d 0a 43  6f 6e 6e 65 63 74 69 6f   859-1  C onnectio   Why is that  because we can not put on the page of JSON a goal like this    In my case I use the manufacturer Connect Me 9210 Digi    I had to use a flag to indicate that one would use non-standard MIME                   p-  theCgiPtr-    fDataType eRpDataTypeOther  It added the new MIME in the variable                   strcpy  p-  theCgiPtr-  fOtherMimeType   text   html  charset   ISO-8859-1       It worked for me without having to convert the data passed by JSON for UTF-8 and then redo the conversion on the page
