Jirka reopened WICKET-1704:
---------------------------
The same bug in class
org.apache.wicket.util.resource.StringBufferResourceStream. Maybe others, that
extends org.apache.wicket.util.resource.AbstractStringResourceStream or
generally implements IStringResourceStream.
> ResourceStreamRequestTarget.configure set wrong ContentLength for non-ascii
> characters

> CharSequence export = DataBase.getInstance().exportDiscounts();
> ResourceStreamRequestTarget target = new ResourceStreamRequestTarget(new
> StringResourceStream(export, "text/plain"));
> target.setFileName("discounts.csv");
> RequestCycle.get().setRequestTarget(target);
> If export contains non-ascii characters. e.g. ěščřžýáíé, is wrong set up the
> ContentLength of the response. ContentLength is set up with number of
> characters, but must be set up with number of bytes. Response on output is
> not all.
> Be sure that byte[].length != "čřžýá".length()
> ResourceStreamRequestTarget.java method configure:
> // WICKET-473 Allow IResourceStream.length() to return -1
> long len = resourceStream.length();
> if (len >= 0)
> {
> // and the content length
> response.setContentLength(len);
> }
