    // (But I don't want to do that for my example..)
    success = sb.WriteFile("qa_output/norwegian_chars.txt","windows-1252",false);

    // Note:  Windows-1252 is a 1-byte per char encoding, which means it's only capable of representing
    // those chars in Western European languages.   See https://en.wikipedia.org/wiki/Windows-1252
    // 
    // utf-8 is an encoding that can handle chars in any language, including Chinese, Korean, Japanese, Arabic, Hebrew, Greek, etc.
    // If a text file contains chars in these other languages, obviously it cannot be converted to windows-1252 because
    // there are only 256 chars that can possibly be represented in a 1-byte per char encoding.
