Answer 1

What this person said:

Encoding.ASCII.GetString(Encoding.GetEncoding(1251).GetBytes(text));

It actually splits the likes of å which is one character (which is character code 00E5, not 0061 plus the modifier 030A which would look the same) into a plus some kind of modifier, and then the ASCII conversion removes the modifier, leaving the only a.

Answer 2

The CodePage of Greek (ISO) can do it

The information about this codepage is into System.Text.Encoding.GetEncodings(). Learn about in: https://msdn.microsoft.com/pt-br/library/system.text.encodinginfo.getencoding(v=vs.110).aspx

Greek (ISO) has codepage 28597 and name iso-8859-7.

Go to the code... \o/

string text = "Você está numa situação lamentável";

string textEncode = System.Web.HttpUtility.UrlEncode(text, Encoding.GetEncoding("iso-8859-7"));
//result: "Voce+esta+numa+situacao+lamentavel"

string textDecode = System.Web.HttpUtility.UrlDecode(textEncode);
//result: "Voce esta numa situacao lamentavel"

So, write this function...

public string RemoveAcentuation(string text)
{
    return
        System.Web.HttpUtility.UrlDecode(
            System.Web.HttpUtility.UrlEncode(
                text, Encoding.GetEncoding("iso-8859-7")));
}

Note that... Encoding.GetEncoding("iso-8859-7") is equivalent to Encoding.GetEncoding(28597) because first is the name, and second the codepage of Encoding.
