FaceletsRendered$Context.wrap() calls facesContext.setResponseWriter with null character encoding. This causes HtmlRenderKitImpl.createResponseWriter to default to ISO-8859-1 encoding which further causes the usage of UnicodeEncoder (delegate.write(String) in MailResponseWriter.write(String)) later on which translates äää --> | // Wrap the ResponseWriter | originalResponseWriter = facesContext.getResponseWriter(); | facesContext.setResponseWriter(facesContext.getRenderKit().createResponseWriter(writer, | null, null)); | | Class org.apache.myfaces.shared_impl.renderkit.html.HtmlResponseWriterImpl.java: | | public void write(String str) throws IOException | { | closeStartTagIfNecessary(); | // empty string commonly used to force the start tag to be closed. | // in such case, do not call down the writer chain | if (str.length() > 0) | { | // Don't bother encoding anything if chosen character encoding is UTF-8 | if (UTF8.equals(_characterEncoding)) _writer.write(str); | else _writer.write(UnicodeEncoder.encode(str) ); | } | } | View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4090075#...
