How to avoid escaping character in RestSharp?

I am writing a small application that sends data to a server through REST API as simple URL calls. I use the RestSharp library to do this. My problem is, that some data strings I am sending include the / character. I can't leave the character as it is, since the called URL would then be invalid. But when I replace it with %2F (which is then translated back on the server side), the RestSharp replaces the % character again, giving %252F. The Rest call than fails since server is missing the backslash.

I have searched the web but found no working solution to this problem. Do you have any idea how to solve it, without using different library and rewriting it myself? Also, not using the backslash is NOT an option.

My code is here:

using RestSharp;  //Version 104       

private string RestRequest(string URL, RestSharp.Method Method)
{
    var Client = new RestClient();
    Client.Authenticator = new HttpBasicAuthenticator(ID, Password);
    var Request = new RestRequest(URL, Method);
    IRestResponse Response = Client.Execute(Request);
    return Response.Content;
}

Sample URL that is passed to the function:

htp://localhost:8080/api/jsonws/knowledge-base-portlet.kbarticle/add-kb-article/portlet-id/1_WAR_knowledgebaseportlet/parent-resource-class-name-id/20704/parent-resource-prim-key/20200/title/SomeTitle/url-title/%2FTitle/content/SomeContent

After snooping around Resharper's Github issues, like this one, it seems you have to use RestRequest.AddURLSegment(). Tested with RestSharp v. 104.0.0

var url = "http://localhost:4422/api/jsonws/knowledge-base-portlet.kbarticle/add-kb-article/portlet-id/1_WAR_knowledgebaseportlet/parent-resource-class-name-id/20704/parent-resource-prim-key/20200/title/SomeTitle/url-title/{segment}/content/SomeContent";

var Client = new RestClient();
var Request = new RestRequest(url,Method.GET);
Request.AddUrlSegment("segment", "%2Ftitle");

I don't know if it's possible for you to pass multiple arguments. If you cannot, the simplest scenario would be splitting by %2F and concatenate multiple arguemnts. Something like this:

private string RestRequest(string URL, RestSharp.Method Method)
{
    var Client = new RestClient();

    string requestUrl;

    bool hasBackslashArgument = ParseEncodedBackSlash(URL, out requestUrl);

    RestRequest request;
    if (hasBackslashArgument)
    {
        request = new RestRequest(requestUrl, Method);
        request.AddUrlSegment("segment", "%2F");
    }
    else
    {
        request = new RestRequest(URL, Method);
    }

    IRestResponse response = Client.Execute(request);
    return response.Content;
}

private bool ParseEncodedBackSlash(string url, out string preformattedString)
{
    preformattedString = null;

    var urlSegments = url.Split(new string[] { "%2F" }, StringSplitOptions.None);

    if (urlSegments.Length == 0) return false;

    preformattedString = string.Join("{segment}", urlSegments);
    return true;
}
