Replace a list of invalid character with their valid version (like tr)

I need to do something like this dreamed .trReplace:

  str = str.trReplace(\"áéíüñ\",\"aeiu&\");

It should change this str

Answer 1

I did something similar for ICAO Passports. The names had to be 'transliterated'. Basically I had a Dictionary of char to char mappings.

Dictionary mappings;

static public string Translate(string s)
{
   var t = new StringBuilder(s.Length);
   foreach (char c in s)
   {
      char to;
      if (mappings.TryGetValue(c, out to))
         t.Append(to);
      else
         t.Append(c);
    }
    return t.ToString();
 }
