Why doesn't Đ get flattened to D when Removing Accents/Diacritics

Question

I\'m using this method to remove accents from my strings:

static string RemoveAccents(string input)
{
    string normalized = input.Normalize(NormalizationFo         


        

Answer 1

"D with stroke" (Wikipedia) is used in several languages, and appears to be considered a distinct letter in all of them -- and that is why it remains unchanged.
