I have a Wicket app with some pages containing accented chars, entered as UTF-8, e.g. "résumé".
When I debug the app via the traditional Wicket Start.java class (which invokes an embedded Jetty server) all is good. However when I try deploying to a local Tomcat instance, it renders as "résumé".
My document looks like:

Here's what curl -I returns for the page when running on Jetty:
HTTP/1.1 200 OK
Content-Type: text/html; charset=utf-8
Content-Language: en-US
Pragma: no-cache
Cache-Control: no-cache, max-age=0, must-revalidate
Content-Length: 13545
Server: Jetty(6.1.25)
And here's what Tomcat returns:
HTTP/1.1 200 OK
Server: Apache-Coyote/1.1
Pragma: no-cache
Cache-Control: no-cache, max-age=0, must-revalidate
Content-Type: text/html;charset=UTF-8
Content-Language: en-US

The problem is that Wicket doesn't detect the encoding of the markup files correctly. They are encoded as UTF-8, so non-ASCII chars are represented by two bytes. But Wicket doesn't know that and reads them as two separate characters. Those two characters are then encoded as UTF-8 again in the response. Since the "square root" characters is not ANSI itself you should actually see three bytes per é in the response.
Anyway, you need to fix this markup encoding interpretation. Checkout the Wicket source code for XMLReader#init().
It reads like Wicket tries three things the find out about the encoding of a markup file:
<?xml ... ?> declaration in beginning of the markup file. (Missing for you?)Application#getMarkupSettings().setDefaultMarkupEncoding(String)
It looks like are missing 1 and 2 at the moment so Wicket falls back to 3 which doesn't work in your case. So try any of the other two.
