将包含带重音符号的单词的字符串列表添加到 RichEditText 框的正确方法

Question

I am trying to add a list of strings that contain special characters such as accents to a RichEditText box. To be exact, it is list of peoples names. Some are in French & Spanish for instance. Unfortunately, these special characters are showing up incorrectly.

I am currently do the following:

aRichEditTextBox.Lines = nameList.ToArray();

For instance... Instead of "Añazgo", I am getting this "A�azgo".

What is the proper or best way to fix this issue?

you have to use an RTF format for the richtextbox to recognize those special character, use this method that came from here - RichTextBox and special chars c#

static string GetRtfUnicodeEscapedString(string s)
{
    var sb = new StringBuilder();
    foreach (var c in s)
    {
        if(c == '\\' || c == '{' || c == '}')
            sb.Append(@"\" + c);
        else if (c <= 0x7f)
            sb.Append(c);
        else
            sb.Append("\\u" + Convert.ToUInt32(c) + "?");
    }
    return sb.ToString();
}

richtextbox1.Rtf = GetRtfUnicodeEscapedString(TextString);
