Parse failures with special characters in untyped data

[mikepizzo]

Attempting to deserialize an untyped string containing special characters fails.

Assemblies affected

WebAPI 6.x, ODataClient

Reproduce steps

string requestUri = baseUri + "/entityset";
string payload = "{\"stringProperty\":\"[t@xt'',,][']other::]mo}{retext\"}";
HttpRequestMessage request = new HttpRequestMessage(HttpMethod.Patch, requestUri);
request.Content = new StringContent(payload);
request.Content.Headers.Add("Content-Type","application/json");

HttpResponseMessage response = this.Client.SendAsync(request).Result;
string result = response.Content.ReadAsStringAsync().Result;

Expected result

string would be deserialized successfully

Actual result

Exception is thrown that string is invalid format.

Additional details

As of ODataLib V7, String/numeric data in a JSON Payload that isn't described by metadata or @odata.type is now read as an ODataUntypedValue. WebAPI and ODataClient attempt to parse this value using ODataUriUtils, but that code doesn't properly ignore special characters inside double-quotes (it expects single quotes, as in a URI) and thus fails if the string property contains properties such as brackets, commas, or braces.
