Convert a Unicode string to an escaped ASCII string

Question

How can I convert this string:

This string contains the Unicode character Pi(π)

into an escaped A

Answer 1

For Unescape You can simply use this functions:

System.Text.RegularExpressions.Regex.Unescape(string)

System.Uri.UnescapeDataString(string)

I suggest using this method (It works better with UTF-8):

UnescapeDataString(string)
