Re: AW: JSF support East Asian characters ?

Thanks!
 
I followed the link and tried the filter solution, unfortunately it did not work for me.
all East Asia characters are still question marks. have you tried East Asia characters in your environment, such as Chinese characters?
 
I tried the following JSP outside JSF. It worked great.  I typed Chinese characters into the input box, and click submit, they displayed back correctly in Chinese, both text and inside the input box. But it did not work in JSF environment.
 
Name: (chinese characters)
Name:[input box]
(submit button)
 
What is difference between regular JSP and JSF in terms of encoding? anything to do with locale? JSF view root has a locale.
 
Thanks!

Hi!

I had to implement a "CharsetFilter" like mentioned here: http://wiki.apache.org/tomcat/Tomcat/UTF-8 (had some problems with "east-european" characters)!

Hope this helps,

Betreff: Re: JSF support East Asian characters ?

Hi Laurie,
 
Thanks.
I added the following to the beginning of each jsp page.
 
<%@ page language="java" contentType="text/html; charset=UTF-8" %>
 
After the page shows up, the browser says UTF-8. This is great.
 
when I typed in some chinese characters using InputText, and left another InputText empty(required) that would cause validation error and force JSF to re-display the page,  the chinese characters became question marks(?) after display back.
 
The page says UTF-8. Will browser(IE) encode everything in UTF-8? How about server-side (JSF)? any character conversions?
 
I tried to add encoding="UTF-8" to , but it is not allowed.
 
Thanks for help.

If the inputText component has an initial value, it will be encoded
server-side using the view's output encoding. When you submit the form,
the browser will encode the current value of the inputText using
whatever encoding it chooses to submit with -- usually the same as the
encoding of the page containing the form.

So it looks like you're sending the browser a page that's encoded as
ISO-8859-something, not UTF-8. That wont work for Asian characters, of
course.

That's in your 'meta' tag in the HTML 'head'? What do you have in your
JSP to specify the page encoding, other than the meta tag? Are you using
a page directive? The meta tag is not enough by itself to tell the JSP
engine to use UTF-8 encoding.

The JSP engine needs to know the correct output encoding to use. If it's
using one encoding (ISO-8859-?), but your meta tag specifies the page
uses a different encoding (UTF-8), things are going to get messed up;
the data is sent in IS0-8859-? but the browser is trying to decode it
using UTF-8.
