The default character encoding for SiteMesh is ISO-8859-1. Also, SiteMesh assumes that the underlying servlet container encoding is also configured to ISO-8859-1.
To support an international market, you can switch to the new standard UTF-8.
The process of using UTF-8 requires requires adjustments to the following layers,
- Set Files and Workspace to UTF-8
- Servlet Container
- Server Operating System
- Server Database if one is being used
Following this tutorial it will be clearly evident if UTF-8 is working. As such, we will stop at each layer to see the results of our changes. It may be the case that the other layers already default to UTF-8.
Create a UTF-8 Web Page
The very first step is to create a UTF-8 page and identify if there are issues.
Verify the Encoding
Load page in Firefox 2.x or higher and click View, Character Encoding. The dot in the menu will indicate which encoding is being used by Firefox.
Inform the browser that the page contents are of a specific character set. You should do this anyway as a general practice.
This is done by specifying a meta tag in the HEAD element of the html page,
Test to see if this resolved the issue. If not continue to the next step.
Set the JSP response header to UTF-8,
Test. Often this resolves the issue.
Use a Custom Servlet Filter
Servlet Filter patch to SiteMesh, though I am not convinced this actually is necessary with current Tomcat (6.0.33) versions - http://blog.sidu.in/2007/05/tomcat-and-utf-8-encoded-uri-parameters.html
