You could simply replace diacritics with alphabetic (near-)equivalences, and then use use your current regex.

See for example:

How do I remove diacritics (accents) from a string in .NET?

static string RemoveDiacritics(string input)
{
    string normalized = input.Normalize(NormalizationForm.FormD);
    var builder = new StringBuilder();

    foreach (char ch in normalized)
    {
        if (CharUnicodeInfo.GetUnicodeCategory(ch) != UnicodeCategory.NonSpacingMark)
        {
            builder.Append(ch);
        }
    }

    return builder.ToString().Normalize(NormalizationForm.FormC);
}

string s1 = "Renato Núñez David DeJesús Edwin Encarnación";
string s2 = RemoveDiacritics(s1);
// s2 = "Renato Nunez David DeJesus Edwin Encarnacion"
