Notepad is not a particularly feature rich editor. It will attempt to guess the document encoding, sometimes with unexpected results. "Plain text" documents don't carry any metadata about their encoding which gives them certain limitations. Windows apps (Notepad included) often rely on the byte-order-mark (U+FEFF or "\uFEFF" in Java strings) to determine if the encoding is a Unicode format. That might help out Notepad; it's going to be useless for your web page problem.

The HTML 4 spec defines how output encoding should be set. You should set the Content-Type HTTP header in addition to specifying the meta encoding.

You don't mention what you're using in your web app. A servlet should set the content type setContentType("text/html; charset=UTF-8"); a JSP should use the page directive to do the same. Other view technologies will provide similar mechanisms.

byte[] utf8Bytes = list.get(i).getBytes("UTF-8");
out.write(new String(utf8Bytes, "UTF-8"));

This code performs some useless operations; it transcodes character data from UTF-16 to UTF-8, then back from UTF-8 to UTF-16, then writes data to a Writer (which will transcode the UTF-16 to UTF-8 again). This code is equivalent:

String str = list.get(i);
out.write(str);

Use a PrintWriter to get newline support.
