ZERO WIDTH SPACE in Json

Question

I'm trying to deal with JSON and I found /u200b (Zero width space) right before double values. I cant pares it right now, even setting the filed type to String. Here I can easily remove it, but how to deal with downloading content from a server?

  String testJson = "{" +
            "    \"name\": \"Aarhus\"," +
            "    \"latitude\": \u200B56.3," +
            "    \"longitude\": \u200B10.619," 
            " }";

You won't be able to parse a string that doesn't have quotes around it, and numbers are not supposed to have any characters besides digits, minus etc. - so what you have here is not valid JSON. — RealSkeptic, May 12 '16 at 18:16
Yes, I know. But it is like that on a server and I have to deal with it as it is. I'm trying to download it as a String and later on remove this values. — Serafins, May 12 '16 at 18:18

Use the following replacement if you already have your data in a string.

testJson =testJson.replaceAll("\u200B", "");

If you need to load data from url first, then some clever ways are discussed here: Read url to string in few lines of java code

with code above yes.. but now when instead of String you have URL – Serafins May 12 '16 at 18:56
Can't you convert it to a huge string and remove the zero-width spaces before parsing it as JSON? – Bruno Toffolo May 12 '16 at 19:01
@Serafins I just added link to hints about loading data from URL – Aleksei Egorov May 12 '16 at 19:23
apparently it doesn't work. As soon as I figured it out. I will accept your answer – Serafins May 12 '16 at 19:50
@Serafins give more info: what have you tried, what result etc – Aleksei Egorov May 13 '16 at 10:09

You can try to use Jackson, it has many options such as FAIL_ON_UNKNOWN_PROPERTIES and ACCEPT_SINGLE_VALUE_AS_ARRAY. It might help
