Wrong. My mail client chose to encode it in UTF-8. But that doesn't change the
fact that ISO-8859-1 contains the ¢ sign at position 162.

It is.

Using an entity reference is just one way to get "special" characters
transmitted to the client. But this will only work if this entity reference
is defined/recocgnized/interpreted in the output format used - for example in
HTML. For other output formats - for example plain text - this will obviously
be useless.
Since - in my experience - modern clients on modern OSes can handle correctly
encoded input just fine (if they are told how it's encoded), I see no general
need to cope with entity references. It all boils down to the fact that the
encoding declared in the HTTP header and the encoding actually used have to
match.
So I'd also stick with Ronald's proposal and create correctly encoded output.
The following - if saved as UTF-8 - should work as expected:
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Display a cent</title>
</head>
<body>
<p>These are two cents: ¢ ¢
</body>
</html>
BTW: it isn't strictly neccessary to use UTF-8. Using a charset that contains
all symbols used is enough. This mail for example should use ISO-8859-1 as
charset and still contain the literal cent sign above correctly encoded.
Nevertheless I'd prefer UTF-8 on the web as a more universal approach.

mks

This is not a matter of saving the jsp/html file on server with the good
charset, this is a matter of using the correct entity reference (¢)
which is supposed to be displayable by any html 2.0 compliant browser.

There are more possibilities for the same thing. In the original question there is no mention about where the character is coming from. If it is something an user submits in a form and is stored in the database and then displayed in another webpage you can not asume the user to type ¢.

This is not a matter of saving the jsp/html file on server with the good
charset, this is a matter of using the correct entity reference (¢)
which is supposed to be displayable by any html 2.0 compliant browser.

Assuming you have this Character Set declaration in your html head
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
use
U+00A2

Hello,
Use the method ServletResponse.setCharacterEncoding("UTF-8") in a Servlet or contentType="text/html; charset=UTF-8" in a jsp page.
http://java.sun.com/products/jsp/syntax/1.2/syntaxref1210.html#15653
But charset issues are tricky because all you files need to use a known charset. And if you use a database it needs to have a supported charset also.
If your editor saves files in iso-8859-1 the problem is already there and the browser wil never see the right character. So you need to debug where the character is correct for the last time.
Ronald.

Hello,
Use the method ServletResponse.setCharacterEncoding("UTF-8") in a Servlet or contentType="text/html; charset=UTF-8" in a jsp page.
