boost: read_json: reading multiple lines

When reading the below JSON data, am getting invalid code sequence exception in read_json.

{
   "_ID":"18",
   "_Record":"1",
   "_BreakPageMessage":"abcd: 137
     Product: ID: 1234
     Description: 23456 abcdfm
     CustomerId: 23456
     Component Id: 3456
     Description: 12345 Admn RC - up
     count: 40
     Sides 2
     Tarnish:
     size: 125 x 205
    Memo:"
}

_BreakPageMessage property has multiple lines. If we give it as single line everything works fine. This _BreakPageMessage doesn't have any umlaut characters.

boost::property_tree::read_json( file, pt );

Can anyone tell is there anyway to read json that has multiple lines of property data using boost.We are using C++ and boost.

Newlines are not valid characters in JSON strings, your data isn't JSON.

You could escape them

{
   "_ID":"18",
   "_Record":"1",
   "_BreakPageMessage":"abcd: 137\r\n     Product: ID: 1234\r\n     Description: 23456 abcdfm\r\n     CustomerId: 23456\r\n     Component Id: 3456\r\n     Description: 12345 Admn RC - up\r\n     count: 40\r\n     Sides 2\r\n     Tarnish:\r\n     size: 125 x 205\r\n    Memo:"
}

or use a sub-object

{
   "_ID":"18",
   "_Record":"1",
   "_BreakPageMessage":{
      "abcd": 137,
      "Product": { "ID": 1234 },
      "Description": "23456 abcdfm",
      "CustomerId": "23456",
      "Component Id": "3456",
      "Description": "12345 Admn RC - up",
      "count": "40",
      "Sides": "2",
      "Tarnish": { size: "125 x 205" },
      "Memo":""
   }
}
