As you might infer, URIEncoding="UTF-8" only work on the Uri part, and
thus affect only GET. The post is decoded using the browser provided
"content-encoding". Most borwser don't bother to set that header.
Behaviour of tomcat is to then use some default (ISO-8859-1). Best way
to ensure tomcat will use UTF-8 for post decoding is to force it using
request.setCharacterEncoding("UTF-8"), before any call to
getParameter(s). a filter or a valve might be a good place :)
btw, be carefull, struts (i see you use struts) tends to also have his
default behaviour when decoding POST :)

Hi there,
I am having some issue with submitting foreign language fonts in HTML form
to Tomcat.
If I set up the FORM with method="GET" everything works just fine. However,
when I use
POST, things don't work - I get garbled characters in my servlet from the
FORM.
In the example below, I am showing the headers for both
GET and POST - the character being sent is a single lower case letter "f" in
cyrillic.
************************************************
The POST method does not work - gives garbled characters - please note that
the mytext is PROPERLY ENCODED IN BOTH methods - GET and POST,
so I don't think that it is a browser issue (i think that my HTML is ok
too).

This is the request using GET - this works just fine - the servlet gets
mytext nicely decoded...

***********************************************
My HTML (rendered from the JSP)
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
</head>
<body>
<form name="InputLanguageForm" method="POST"
action="/Inter/takeText.do" accept-charset="UTF-8" >
<input type="text" name="mytext" value="">
<input type="submit" value="Do it">
</form>
</body>
</html>
************************************************
This is the configuration of the Tomcat Connector - if I REMOVE URIEncoding,
both GET and POST don't work any more.
<Connector port="8080" protocol="HTTP/1.1"
connectionTimeout="20000" URIEncoding="UTF-8"
redirectPort="8443" />
************************************************
Thanks for any insight you can give me here... I really don't want to
change ALL my forms to GET - there should be
an easier (and more natural) fix for this.
Thanks, Alex.
