Facebook Graph API - non English album names

Question

I am trying to do a simple thing - get all my albums. the problem is that the album names are non-English ( they are in Hebrew ).

The code that retrieves the albums :

string query = "https://graph.facebook.com/me/albums?access_token=...";
string result = webClient.DownloadString(query);

And this is how one of the returned albums looks like :

{
     "id": "410329886431",
     "from": {
        "name": "Noam Levinson",
        "id": "500786431"
     },
     "name": "\u05ea\u05e2\u05e8\u05d5\u05db\u05ea \u05d2\u05de\u05e8 \u05e9\u05e0\u05d4 \u05d0",
     "location": "\u05e9\u05e0\u05e7\u05e8",
     "link": "http://www.facebook.com/album.php?aid=193564&id=500786431",
     "count": 27,
     "type": "normal",
     "created_time": "2010-07-18T06:20:27+0000",
     "updated_time": "2010-07-18T09:29:34+0000"
  },

As you can see the problem is in the "name" property. Instead of Hebrew letters I get those codes (These codes are not garbage, they are consistent - each code probably represents a single Hebrew letter). The question is , how can I convert those codes to a non-English language ( In my case, Hebrew). Or maybe the problem is how I retrive the albums with the webClient object. maybe change webclient.Encoding somehow?

what can I do to solve this problem ?

Thanks in advance.

Answer 1

These are Unicode character codes. The \u sequence tells the parser that the next 4 characters are actually form a unicode character number. What these characters look like will depend on your font, if someone does not have the correct font they may just appear as a lot of square boxes. That's about as much as I know, Unicode is complicated.

Answer 2

That's how Unicode is represented in JSON (see the char definition in the sidebar). They are escape sequences in which the four hex digits are the Unicode code point of the character. Note that since there's only four hex digits available, only Unicode characters from the BMP can be represented in JSON.

Any decent JSON parser will transform these Unicode escape sequences into properly encoded characters for you - provided the target encoding supports the character in the first place.
