Wicket WebResponse Attachment Header with UTF-8 charackers? - encoding

Question

In wicket project I use request handler for file downloading. Everything is works good until I have file with non standard encoding like utf-8.
I use this code for generate response
#Override
public void respond(IRequestCycle requestCycle)
{
WebResponse response = (WebResponse) requestCycle.getResponse();
response.setAttachmentHeader(briefcaseDocument.getName());
response.setContentType(briefcaseDocument.getMimeType());
response.setContentLength(briefcaseDocument.getSize());
InputStream inputStream = null;
OutputStream outputStream = null;
try
{
inputStream = briefcaseDocument.getInputStream();
outputStream = response.getOutputStream();
IOUtils.copyLarge(inputStream, outputStream);
}
catch (Exception e)
{
throw new RuntimeException("unable to push file content", e);
}
finally
{
IOUtils.closeQuietly(inputStream);
IOUtils.closeQuietly(outputStream);
}
}
but if document has special characketrs I get empty file name. For example:
ćććć is:
Content-Disposition attachment; filename=" ";
ćwiek is:
Content-Disposition attachment; filename=" wiek";
I read this stack topic and change code like this:
String fileName = briefcaseDocument.getName();
String encoded = URLEncoder
.encode(briefcaseDocument.getName(), "UTF-8");
response.setHeader("Content-Disposition","attachment" +
((!Strings.isEmpty(fileName)) ? ("; filename=\"" + fileName + "\"; filename*=UTF-8''"+encoded) : "" ));
and then I get as result:
Content-Disposition attachment; filename=" "; filename*=UTF-8''%C4%87%C5%BC
and file name present good, but I don't feel good with this solution ;) How to make wicket set file name properly?

According to http://greenbytes.de/tech/tc2231/ this is the proper way.
Since 7.0.0-M1 (https://issues.apache.org/jira/browse/WICKET-4934) Wicket does this automatically for you.
