            Console.WriteLine(specialcharactersdata);


            using (MemoryStream ms = new MemoryStream(System.Text.ASCIIEncoding.UTF8.GetBytes(specialcharactersdata)))
            {
                StreamWriter sw = new StreamWriter(ms);
                sw.Flush();
                ms.Position = 0;
                StreamReader sr = new StreamReader(ms);
                string myStr = sr.ReadToEnd();
              
                Console.WriteLine(myStr);
                Console.Read();
            }

By default, the console doesn't support UTF8 / Unicode characters; it only supports characters in the current code-page.

Depending on your OS, you might be able to fix it by setting the Console.OutputEncoding property[^] to System.Text.Encoding.UTF8 before writing the values. For some characters, you might also need to install extra fonts, and change the console font.

Hi Richerd,
1. I have moved to this code to MVC4 application and try to add Header to the below code
TransferUtilityUploadRequest uploadRequest = new TransferUtilityUploadRequest();
uploadRequest.BucketName = sourceBucketName.ConfigValue.ToString();
uploadRequest.Key = fileFullName;

Stream tmpStream = new MemoryStream(System.Text.Encoding.UTF8.GetBytes(downloadData));
tmpStream.Seek(0, SeekOrigin.Begin);
StreamReader sReaderData = new StreamReader(tmpStream);

Need to Add this header this uploadRequest.Headers.ContentEncoding = Encoding.Unicode;
but getting excecption
If i add this header then the data should display in my excel file.

Solution 1

That's because none of those character exist in the ASCII encoding.

Try using UTF8 instead!

-------------

Ok - still confused. I've tried your code, and the text gets preserved just fine. The special characters are not going to be an issue unless you go back to something like ASCII. I've rewritten it slightly:

string specialcharactersdata = @"Á,õn O'kim José Nuñez JOSNUÑ44  ";
Console.WriteLine(specialcharactersdata);
using (MemoryStream ms = new MemoryStream())
{
    StreamWriter sw = new StreamWriter(ms);
    sw.WriteLine(specialcharactersdata);
    sw.Flush();
    ms.Position = 0;
    StreamReader sr = new StreamReader(ms);
    string myStr = sr.ReadToEnd();
    Console.WriteLine(myStr);
    Console.Read();
}

Which produces the output I'd expect, which seems to align with what is required in your latest comment but not with the original question.

I have used the below code
using (MemoryStream ms = new MemoryStream(System.Text.Encoding.UTF8.GetBytes(specialcharactersdata)))
but this code text is not displaying special characters
Á,õn O'kim José Nuñez

Rob Philpott 23-Jan-19 8:25am

Sorry, I think I misread your post. But I don't understand what you trying to do. You are trying to convert "Á,õn O'kim José Nuñez" to "JOSNUÑ44"? I don't see the relationship between the two.

DGKumar 23-Jan-19 8:44am

Á,õn O'kim José Nuñez JOSNUÑ44 this is complete string

Rob Philpott 23-Jan-19 8:17am

Give me a moment, I'll try it...

DGKumar 23-Jan-19 8:43am

I have a string like below
Á,õn O'kim José Nuñez

I need to pass the data by using Memory stream as below
using (MemoryStream ms = new MemoryStream(System.Text.Encoding.UTF8.GetBytes(specialcharactersdata)))

if i use this i am getting missed characters string
like below

A,on O'kim but actual string is Á,õn O'kim which is modified after using the code

DGKumar 24-Jan-19 3:55am

Hi Rob,
Even though the same text what i have tried that is also not displaying in console output window.
