Прошу прощения, я привёл не корректный пример, каюсь. Не учёл, что значения могут содержать знак запятой, поэтому Split использовать нельзя.
И ещё, у тэга <form> есть полезный аттрибут "accept-charset"...
Предлагаю следующий код для RemotePost.cs:
using System;
using System.Collections.Specialized;
using System.Web;
using Nop.Core.Infrastructure;

public string Url { get; set; }
/// <summary>
/// Gets or sets a method
/// </summary>
public string Method { get; set; }

public string FormName { get; set; }
/// <summary>

_httpContext.Response.Write(string.Format("<form name=\"{0}\" method=\"{1}\" action=\"{2}\" accept-charset=\"{3}\">", FormName, Method, Url, AcceptCharset));
