[SUMMARY] Encoding form data

[Bert Van Kets]

Cocoon does not support non-US characters when posting data to the server.
Characters like è (e accent grave) are translated to two strange characters when checking the posted data.
iso-8859-1 is the default encoding for Cocoon and it does support all necessary West European characters (thanks to Bruno for pointing this out). You can find out more on iso-8859-1 on http://www.bbsinc.com/iso8859.html
If you need support for other characters you will need to replace iso-8859-1 with UTF-8 which has Unicode support. More on UTF can be found at http://www.columbia.edu/kermit/utf8.html

When you create a webform and post to a pipeline that has a request generator and an XML serializer you will see that posted data is not correctly presented. To correct this you need to add the request.setCharacterEncoding method to set the encoding for the request data. This method is captured in the setCharacterEncodignAction action.

To use it simply add

<map:action name="set-encoding" src="org.apache.cocoon.acting.SetCharacterEncodingAction"/>

to the action component block

Then add this at the beginning of every pipeline that catches requested non-ASCII data

<map:act type="set-encoding">
<map:parameter name="form-encoding" value="iso-8859-1"/>
</map:act>

Of course you need to replace "iso-8859-1" with "UTF-8" if you need to use that encoding.

Another important thing is that you must make sure the data is sent out to the browser with the correct encoding in the first place. To achieve this add the encoding to the XML and the (x)html serializers.

<map:serializer mime-type="text/html" name="html" src="org.apache.cocoon.serialization.HTMLSerializer" pool-grow="4" pool-max="32" pool-min="4" logger="sitemap.serializer.html">
<buffer-size>1024</buffer-size>
<encoding>iso-8859-1</encoding>
</map:serializer>

This should do it!

Have fun.
Bert
