As with any software project, start with the requirements. Until you know
exactly what you want to achieve, you can't really plan to achieve it.
Are you talking about a fully-featured web-browser for veiwing any page on
the public Internet with full JavaScript and CSS support? That's a huge
task (look how long it took the Mozilla Foundation with hundreds of
volunteers). If it's just for viewing specific pages that you have some
control over, then things start to become more manageable since you can
restrict yourself to well-formed XHTML and not worry about having to parse
the tag soup. Even so, just the layout engine for that is a big project.

for a small browser. IIRC it is around 200 lines.

I just did a little tweaking with your code, but there is something I
still don't get right, namely:
..
Why is it you can not display "text/html; charset=UTF-8" or
"text/html; charset=GB2312" encoded pages, even if per javadocs:
..
// __
http://java.sun.com/j2se/1.4.2/docs/api/javax/swing/JEditorPane.html
// __
http://java.sun.com/j2se/1.4.2/docs/api/javax/swing/JEditorPane.html#setPage
// __
http://java.sun.com/j2se/1.4.2/docs/api/javax/swing/JEditorPane.html#setContentType
..
text/html: HTML text. The kit used in this case is the class
javax.swing.text.html.HTMLEditorKit which provides HTML 3.2 support.
..
Weren't "text/html; charset=utf-8" encoded pages supported by HTML
3.2? Something like:
..
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 3.2 Final//EN">
<html>
<head>
<title>HTML 3.2 and text/html; charset=utf-8 test</title>
<meta http-equiv="content-type" content="text/html; charset=utf-8" />
<meta http-equiv="Content-Style-Type" content="text/css" />
</head>
....
</html>
..
also I don't quite understand what is meant in the specification with:
..
setContentType: public final void setContentType(String type)
..
Sets the type of content that this editor handles. This calls
getEditorKitForContentType, and then setEditorKit if an editor kit can
be successfully located. This is mostly convenience method that can be
used as an alternative to calling setEditorKit directly.
If there is a charset definition specified as a parameter of the
content type specification, it will be used when loading input streams
using the associated EditorKit. For example if the type is specified as
text/html; charset=EUC-JP the content will be loaded using the
EditorKit registered for text/html and the Reader provided to the
EditorKit to load unicode into the document will use the EUC-JP charset
for translating to unicode. If the type is not recognized, the content
will be loaded using the EditorKit registered for plain text,
text/plain.
..
How can you display non-ASCII characters using a basic java-based
browser like this one?

It *can* display such pages. You don't have to specify the encoding.
E. g. point your "browser" to
http://www.ibm.com/gr/el
You'll see a page containing greek glyphs. If not, either your fonts
don't support it or it might be a bug in your java version
If you e.g. use setContentType("text/plain") this method will set the
right EdiorKit (not HTMLEditorKit).
<api>
There are multiple ways to get a character set mapping to happen with
JEditorPane.
1. One way is to specify the character set as a parameter of the
MIME type. This will be established by a call to the setContentType
method. If the content is loaded by the setPage method the content type
will have been set according to the specification of the URL. It the
file is loaded directly, the content type would be expected to have been
set prior to loading.
2. Another way the character set can be specified is in the document
itself. This requires reading the document prior to determining the
character set that is desired. To handle this, it is expected that the
EditorKit.read operation throw a ChangedCharSetException which will be
caught. The read is then restarted with a new Reader that uses the
character set specified in the ChangedCharSetException (which is an
IOException).
It is encoding-aware already.
Please follow the conventions and don't capitalize variable names (it's
jTxtPn not JTxtPn).

If you've problems with reading Chinese characters from a stream, the
character encoding used for reading is wrong.
If you've problems rendering Chinese characters, the used font doesn't
include these.
E.g. the following
import javax.swing.*;
public class Unicode {
public static final void main( String args[] ) {
JFrame frame = new JFrame("Unicode");
frame.setDefaultCloseOperation( JFrame.DISPOSE_ON_CLOSE );
frame.getContentPane().add( new JLabel("\u4e10 \u2704") );
frame.pack();
frame.setVisible( true );
}
}
can be used to display a chinese symbol [1] and a dingbat symbol [2]
(scissors).
Since the fonts I use don't include chinese characters (but dingbat
symbols) I get a small rectangle followed by the scissors.
