I have below readfile() java function to read .htm files

private String readfile(String inputDoc) throws IOException {
    FileInputStream fis = null;
    InputStreamReader isr = null;
    String text = null;
    //open input stream to file
    fis = new FileInputStream(inputDoc);
    isr = new InputStreamReader(fis, "UTF-8");
    StringBuffer buffer = new StringBuffer();
    int c;
    while( (c = isr.read()) != -1 ) {
        buffer.append((char)c);
    }
    text = buffer.toString();
    isr.close();
    return text;
}

Here is example snippet of input doc

<?xml version="1.0" encoding="utf-8"?><html>

<head>

For some reason text string returned from readfile() is <?xml version="1.0" encoding="utf-8"?><html>\r\r\n<head>

but I expect it to be <?xml version="1.0" encoding="utf-8"?><html>\r\n<head>

as it is outlined here newline char in windows \r\n

I ran above function in IntelliJ Idea on Windows 7. (IDEA default encoding is set to UTF-8)

Does anyone know why I get this weird result from readfile(String inputDoc) function for newline

    You get this because it is like this in the input file. Try to open the input file in a hex editor to verify.
