C# Help reading foreign characters using StreamReader

You may also try the Default encoding, which uses the current system's ANSI codepage.

StreamReader reader = new StreamReader(inputFilePath, Encoding.Default, true)

When you try using the Notepad "Save As" menu with the original file, look at the encoding combo box. It will tell you which encoding notepad guessed is used by the file.

Also, if it is an ANSI file, the detectEncodingFromByteOrderMarks parameter will probably not help much.

I had the same problem and my solution was simple: instead of

Encoding.ASCII

use

Encoding.GetEncoding("iso-8859-1")

The answer was found here.

Edit: more solutions. This maybe more accurate one:

Encoding.GetEncoding(1252);

Also, in some cases this will work for you too if your OS default encoding matches file encoding:

Encoding.Default;

Yes, it could be with the actual encoding of the file, probably unicode. Try UTF-8 as that is the most common form of unicode encoding. Otherwise if the file ASCII then standard ASCII encoding should work.
