Converting problem ANSI to UTF8 C#

Question

I have a problem with converting a text file from ANSI to UTF8 in c#. I try to display the results in a browser.

So I have a this text file with many accent characte

Answer 1

This is probably happening because your original string text already contains invalid characters. Encoding conversion only makes sense if your input is a byte array. So, you should read the file as byte array instead of string, or, as Henk said, specify the encoding for reading the file.

Answer 2

My thoughts here is when you save the file in Notepad++ it inserts the Byte-Order-Mark so the browser can infer that it's UTF8 from this. Otherwise you'd probably have to explicitly tell the browser the character encoding, as in the DTD, in XML etc.

Answer 3

Do you have any idea why is this happening?

Yes, you're too late. You need to specify ANSI when you read the string from file. In memory it's always Unicode (UTF16).

Answer 4

When you convert to ASCII you immediately lose all non-English characters (including ones with accent) because ASCII has only 127 (7 bits) of characters.

You do strange manipulation. string in .net is in UTF-16, so once you return string, not byte[] this doesn't matter.

I think you should do: (I guess by ANSI you mean Latin1)

public byte[] Encode(string text)
{
    return Encoding.GetEncoding(1252).GetBytes(text);
}

Since the question was not very clear there is a reasonable remark that you might actually need this one:

public string Decode(byte[] data)
{
    return Encoding.GetEncoding(1252).GetString(data);
}

Answer 5

I would recommend to read this http://www.joelonsoftware.com/articles/Unicode.html.
If you are going to read a ASCII file you need to know the code page of the file.

Answer 6

Also, you can try the following thing. I've changed the type by using notepad+ in the file.
(Encoding->Convert to UTF-8)
It works for me.
