我直接修改了org.zkoss.web.servlet.http包底下的Https类的encodeFilename方法也可以解决这个问题.

    private static String encodeFilename(String flnm) {
        String filename = Strings.escape(flnm, "\"") ;
        [color=red]try {
            filename =URLEncoder.encode(filename, "UTF-8");
        } catch (UnsupportedEncodingException e) {
            e.printStackTrace();
        }[/color]
        return '"' + filename+ '"';
    }

我用的是zk-5.0.5版本.

你这也是一种方式，我也留下我的一种处理方式吧：

Execution ex = Executions.getCurrent();
HttpServletRequest request = (HttpServletRequest) ex.getNativeRequest();
if (request.getHeader("User-Agent").indexOf("MSIE") != -1) {// ie
docFilename = URLEncoder.encode(docFilename, "UTF-8");
} else {// firefox
docFilename = MimeUtility.encodeText(docFilename, "GBK", "B");
}
