How to change diacritic characters to non-diacritic ones [duplicate]

Answer 1

My site inputs data from external sources which have many strange characters. I wrote the following C# function to replace accented characters and strip out non-US keyboard characters using Regex:

    using System.Text;
    using System.Text.RegularExpressions;

    internal static string SanitizeString(string source)
    {
        return Regex.Replace(source.Normalize(NormalizationForm.FormD), @"[^A-Za-z 0-9 \.,\?'""!@#\$%\^&\*\(\)-_=\+;:<>\/\\\|\}\{\[\]`~]*", string.Empty).Trim();    
    }

Hope it helps.
