Replace broken characters

Question

I have a small programm that replace strings that contains umlauts, apostrophes etc.
But sometimes I haven broken strings that contains for example A¶ for ü, A¼ (or Ã¼) for ö, and so on.
Is there a way to fix these strings?

I just tried to use another replace statement

  str = str.Replace("A¶", "ü");
  str = str.Replace("A¼", "ö");
  str = str.Replace("Ã¼", "ö");

But this do not work for me

Just add another `Replace` statement for the character that you're replacing? Not sure I understand what you're asking for here... — ElGavilan, Dec 15 '13 at 06:44
It's late for this but assuming that "ö" decoded as ASCII will give "A¼" then why don't you pick your list of umlauts and apostrophes (you have them for other conversions, right?) then decode each string as ASCII and replace _decoded broken string_ with _original undecoded unbroken string_? — Adriano Repetti, Dec 19 '13 at 16:23

It looks like because they are non-standard characters it is having trouble matching. You will probably have to use Regex.Replace and reference the Unicode value of the characters in your regex: How can you strip non-ASCII characters from a string? (in C#)
