Replacing characters in C# (ascii)

Question

I got a file with characters like these: à, è, ì, ò, ù - À. What i need to do is replace those characters with normal characters eg: à = a, è = e and so on..... This is my c

Answer 1

I often use an extenstion method based on the version Dana supplied. A quick explanation:

• Normalizing to form D splits charactes like è to an e and a nonspacing `
• From this, the nospacing characters are removed
• The result is normalized back to form D (I'm not sure if this is neccesary)

Code:

using System.Linq;
using System.Text;
using System.Globalization;

// namespace here
public static class Utility
{
    public static string RemoveDiacritics(this string str)
    {
        if (str == null) return null;
        var chars =
            from c in str.Normalize(NormalizationForm.FormD).ToCharArray()
            let uc = CharUnicodeInfo.GetUnicodeCategory(c)
            where uc != UnicodeCategory.NonSpacingMark
            select c;

        var cleanStr = new string(chars.ToArray()).Normalize(NormalizationForm.FormC);

        return cleanStr;
    }
}
