    1. Have you checked that your sms gateway supports the unicode. As many gateway provider put some type on the URL so that the gateway understand the actual characters encoding

  4. Thanks .. this article is very useful .. I am a C# developer and implemented your logic in my code .. it worked 🙂 .. Here is the code.. hope this may help others ..

    public string Utf8ToUnicode(string str)
    var unicode = new List();
    var values = new List();
    var lookingFor = 1;
    var ascii = Encoding.UTF8.GetBytes(str);

    for (var i = 0; i < ascii.Length; i++)
    var thisValue = ascii[i];
    if(thisValue == 32)
    if (thisValue < 128)
    var uniStr = ConvertToHex(thisValue);
    unicode.Add((uniStr.Length == 1) ? "%u000" + uniStr : "%u00" + uniStr);
    if (values.Count == 0)
    lookingFor = (thisValue < 224) ? 2 : 3;
    if (values.Count == lookingFor)
    var number = (lookingFor == 3) ?
    ((values[0] % 16) * 4096) + ((values[1] % 64) * 64) + (values[2] % 64) :
    ((values[0] % 32) * 64) + (values[1] % 64
    var uniStr = number.ToString("X");
    unicode.Add((uniStr.Length == 3) ? "%u0" + uniStr : "%u" + uniStr);
    values = new List();
    lookingFor = 1;
    } // if
    } // if
    return string.Join(“”, unicode.ToArray());

  5. Sir am creating a mock test portal for SSC and given the questions in English only but there are so many students who prefer Hindi instead of english and I don’t want to re-type the all questions and options in Hindi, is there any way to display all English typed along with Hindi translation without handling it twice?
