Step two seems ok - but I'd prefer to store a byte array
http://msdn.microsoft.com/en-us/goglobal/cc305145There are some values that are not a char in codepage 1252
Seems to work - but will it be without any problem in the future - I don;t know
internal static void Go()
{
byte[] bytes = new byte[] {0x81, 0x8d, 0x8f, 0x90 };
string s = Encoding.GetEncoding(1252).GetString(bytes);
char[] c = s.ToCharArray();
int l = s.Length;
}
