Question

I am doing a simple ajax call with the YahooUI Javascript library as follows:

YAHOO.util.Connect.setForm('myform');
YAHOO.util.Connect.asyncRequest('POST', url, ...);

Following are the settings in my app:
Tomcat version: 6.0.18

Tomcat server connector : URIEncoding=”UTF-8″
webapp page :

Also stated in YahooUI connector library docs:

setForm will encode each HTML form
field’s name and value using
encodeURIComponent. This results in a
string of UTF-8 encoded, name-value
pairs. NOTE: Setting an HTTP header of
“Content-Type” with a different
charset value will not change the
encoding of the serialized data.encoding of the serialized data.

I can see that the french characters that are being sent as parameters are encoded (in ie7 using iehttpheader tool):

    name=%C3%88%C3%A0%C3%B4 
    testParam=%C3%B4%C3%B4   

For the data :
name: Èàô
and testParam: ôô

But on the server side I am seeing values as following:
ÈàÃÂ

Even if I am converting the string to bytes and then create new string with the charset defined as follows:
String val = new String(oo.getBytes(“UTF-8”));
I am not able to get the exact data as expected.

Note: I have referenced the question below, but was not able to resolve this issue: How to get UTF-8 working in Java webapps? Please guide.

UPDATE:
Calling the decode UTF-8 function as given on W3.org site http://www.w3.org/International/O-URL-code.html is giving me the expected results. I expect Tomcat to be decoding this?.

Since you are using a POST query, URIEncoding="UTF-8" is not applicable here. You need to set a filter to tell Tomcat that your request encoding is UTF-8. You may use, for example, a Spring’s CharacterEncodingFilter (usage, javadoc). Other implementations of such filters can also be found.
