how to display decoded utf-8 string characters back in textbox.

Asked by: tekege

Hello Experts,

Plz help me...
When I get the value of "s_unicode2" in a textbox, it does not convert in it's original format, while when i use response.write or label control it shows it's original value. What can i do so that the decoded string will display porperly in textbox...???

System.Text.Encoding utf_8 = System.Text.Encoding.UTF8;
    // This is our Unicode string:
    string s_unicode = txtReadScript.Text;
    // Convert a string to utf-8 bytes.
    byte[] utf8Bytes = System.Text.Encoding.UTF8.GetBytes(s_unicode);
    // Convert utf-8 bytes to a string.
    string s_unicode2 = System.Text.Encoding.UTF8.GetString(utf8Bytes);
 
    //txtDecodeMsg.Text = s_unicode2;
    Response.Write(s_unicode2);
