problem with latin2
Hi
I'm writing WEB application where I have to use polish fonts. I have set
up input and output encodings to iso-8859-2 in velocity.properties, also
compile application with option -encoding latin2, templates are also
set to iso-8859-2. I also use Postgres (database with option -E latin2).
When I read data from database (which contains polish letters) and show
it in navigator everything is ok.
The problem is when I try to save data from form. After posting it I get
"?" instead of every polish letter when validation fails, and when
validation is ok every polish letter is gone (they are cut).
To specify more I use Struts with Velocity.
Has anyone get any similar problem?

Adding to Daniel's comment, as it is stated in the javadocs, "This
method must be called prior to reading request parameters or reading
input using getReader()." So the only feasible solution I find with
Struts is using a Filter.

And here's an example of what one might look like:
public class PolishFilter implements Filter {
public void doFilter(ServletRequest request, ServletResponse
response, FilterChain chain) throws IOException, ServletException {
request.setCharacterEncoding("iso-8859-2");
chain.doFilter(request, response);
}
}
## I'm leaving out unimplemented methods.

The problems is often that the text goes trough an extra charset
encodings/decodings when you try to examine it for debugging purposes,
and this can obliterate the traces of the root problem. To spot where
exactly the problem happens, print (e.g. log) the text on various phases
(e.g. when you get the request parameters) with *character codes*, that
is, with numbers. Then check if the printed UCS codes are OK at that
point. (As a catalog of UCS codes you may use "UniBook".)

tried and nothing
before reading from request I call
request.setCharacterEncoding("iso-8859-2") and still get "?"

The only problem is when you get input from the browser, is that
correct? ie. Showing Polish statically or from your database with
your template is fine?
If so, you should check the encoding of your request. Does the Polish
characters show when you do request.getParameter("so-and-so")? If
not, you need to set the encoding of your request to latin-2.

Using Filter works for me. :)
