I cannot get any (hex) number in the "0x80"-"0x89" range (inclusive)

"0x83" = UInt16 "131" and that converts to Char (curly) "f". Any
information would be helpful.
String[] hexNum = { "79", "80", "89", "90" };
System.IO.StreamWriter streamWriter = new System.IO.StreamWriter(@"C:
\test.dbf", true, System.Text.Encoding.Default);
foreach (String hex in hexNum)
{
Char hexChar = (Char)UInt16.Parse(hex,
System.Globalization.NumberStyles.HexNumber);
streamWriter.Write(hexChar);
}
streamWriter.Flush();
streamWriter.Close();
Have you looked at the default encoding and what it does to your data?
Since you're writing text characters through an encoding object, it will in some cases encode the characters different than if you just output pure bytes to begin with.
