hello, the following code is to convert from English to Arabic but somehow the Arabic appear as a question mark, but when converting from arbic to English it's work I don't if some one can help me, I will be appreciate

this is for design code

<form id="form1" runat="server">
        <asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
        <asp:Button ID="Button1" runat="server" OnClick="Button1_Click" Text="Button" />
        <asp:Label ID="Label1" runat="server" Text="Label"></asp:Label>

and this is for code behind

What I have tried:

<pre>using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;

public partial class test : System.Web.UI.Page
    protected void Page_Load(object sender, EventArgs e)

     protected void Button1_Click(object sender, EventArgs e)
            TranslateText(TextBox1.Text, "en|ar");//Hindi to English

        public string TranslateText(string input, string languagePair)

            string url = String.Format("{0}&langpair={1}", input, languagePair);

            System.Net.WebClient webClient = new System.Net.WebClient();

            webClient.Encoding = System.Text.Encoding.UTF8;

            string result = webClient.DownloadString(url);
            int index1 = Convert.ToInt32(result.IndexOf("onmouseout=" + '"' + "this." + "style." + "backgroundColor" + "=" + "'" + "#fff" + "'" + '"' + ">"));//onmouseout="'#fff'">
            int index2 = Convert.ToInt32(result.IndexOf("id=" + '"' + "gt-edit" + '"'));
            int index3 = index2 - index1;
            result = result.Substring((index1 + 47), (index3 - 49));
            Label1.Text = result.ToString();

            return result;

? in your output is a presentation problem to do with character encoding in you html or font settings.

Does it work as expected if you do it manually with Google Translate?

Side Note: If Google become aware of what you are doing, and they will, you will find that your website will stop working. The correct way is to use their Google Cloud Translation API[^]

thank u but this for testing and I already solve this by change web client.Encoding = System.Text.Encoding.UTF8; to webClient.Encoding = System.Text.Encoding.GetEncoding("windows-1256");

In Widows Control PAnel.. Regional Option... Administrative Tab... Select in Langauge Non Unicode Programe.. Select the Arabic langauge of that Region

So everyone using the website would have to do this? Not a good solution at all
