If you need to remove diacritics from a string you can do a lot’s of replace like this :
string inputString = "HéllÕ Wôrld !";
var result = inputString.Replace('À', 'A');
Repeat for ÀÁÂÃÄâãäàáÈÉÊËêëèéÌÍÎÏîïìíÒÓÔÖôõöòóÙÚÛÜûüùúÝýÑñç and maybe miss some exotic chars or the Õ in this list !
or you can use this function
public static string RemoveDiacritics(string inputString)
{
//!\\ Warning 'œ' will be replaced with a 'o' not an 'oe'
String normalizedString = inputString.Normalize(NormalizationForm.FormD);
StringBuilder stringBuilder = new StringBuilder();
for (int i = 0; i < normalizedString.Length; i++)
{
Char c = normalizedString[i];
if (System.Globalization.CharUnicodeInfo.GetUnicodeCategory(c) != System.Globalization.UnicodeCategory.NonSpacingMark)
stringBuilder.Append(c);
}
return stringBuilder.ToString();
}
