  • How do you get Matlab to write the BOM (byte order markers) for UTF-16 text files?

    - by Richard Povinelli
    I am creating UTF16 text files with Matlab, which I am later reading in using Java. In Matlab, I open a file called fileName and write to it as follows: fid = fopen(fileName, 'w','n','UTF16-LE'); fprintf(fid,"Some stuff."); In Java, I can read the text file using the following code: FileInputStream fileInputStream = new FileInputStream(fileName); Scanner scanner = new Scanner(fileInputStream, "UTF-16LE"); String s = scanner.nextLine(); Here is the hex output: Offset(h) 00 01 02 03 04 05 06 07 08 09 0A 0B 0C 0D 0E 0F 10 11 12 13 00000000 73 00 6F 00 6D 00 65 00 20 00 73 00 74 00 75 00 66 00 66 00 s.o.m.e. .s.t.u.f.f. The above approach works fine. But, I want to be able to write out the file using UTF16 with a BOM to give me more flexibility so that I don't have to worry about big or little endian. In Matlab, I've coded: fid = fopen(fileName, 'w','n','UTF16'); fprintf(fid,"Some stuff."); In Java, I change the code to: FileInputStream fileInputStream = new FileInputStream(fileName); Scanner scanner = new Scanner(fileInputStream, "UTF-16"); String s = scanner.nextLine(); In this case, the string s is garbled, because Matlab is not writing the BOM. I can get the Java code to work just fine if I add the BOM manually. With the added BOM, the following file works fine. Offset(h) 00 01 02 03 04 05 06 07 08 09 0A 0B 0C 0D 0E 0F 10 11 12 13 14 15 00000000 FF FE 73 00 6F 00 6D 00 65 00 20 00 73 00 74 00 75 00 66 00 66 00 ÿþs.o.m.e. .s.t.u.f.f. How can I get Matlab to write out the BOM? I know I could write the BOM out separately, but I'd rather have Matlab do it automatically. Addendum I selected the answer below from Amro because it exactly solves the question I posed. One key discovery for me was the difference between the Unicode Standard and a UTF (Unicode transformation format) (see http://unicode.org/faq/utf_bom.html). The Unicode Standard provides unique identifiers (code points) for characters. UTFs provide mappings of every code point "to a unique byte sequence." Since all but a handful of the characters I am using are in the first 128 code points, I'm going to switch to using UTF-8 as Romeo suggests. UTF-8 is supported by Matlab (The warning shown below won't need to be suppressed.) and Java, and for my application will generate smaller text files. I suppress the Matlab warning Warning: The encoding 'UTF-16LE' is not supported. with warning off MATLAB:iofun:UnsupportedEncoding;

  • How to use GWT when downloading Files with a Servlet?

    - by molleman
    Hello Guys I am creating a simple project that will allow me to upload and download files using gwt. i am having trouble with the downloading of files that are on my server. For the file upload i used http://code.google.com/p/gwtupload/ and followed the instructions there. My file is stored on the server outside of the website container(on the hard drive), Now when it comes to the downloading of a file, i want a user to press a download button and whatever item is currently selected will download. i dont really know how this will be done i know i need a download servlet public class DownloadAttachmentServlet extends HttpServlet { @Override protected void doPost(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException { // TODO Auto-generated method stub super.doGet(req, resp); } @Override protected void doGet(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException { String fileName = (String) req.getSession().getAttribute("fileName"); YFUser user = (YFUser) req.getSession().getAttribute(TestServiceImpl.SESSION_USER); if (user == null) throw new ServletException("Invalid Session"); InputStream in = null; OutputStream out = resp.getOutputStream(); FileInputStream fIn = new FileInputStream(fileName); byte[] buffer = new byte[4096]; int length; while ((length = in.read(buffer)) > 0){ out.write(buffer, 0, length); } in.close(); out.flush(); } } for the moment i will just pass a fileName string to retrieve the file for testing now i am lost at what to do on the client side, i have a simple public class DownloadFilePanel extends Composite { public DownloadFilePanel(final YFUser user , final String fileName){ final Element downloadIframe = RootPanel.get("__download").getElement(); VerticalPanel content = new VerticalPanel(); content.add(new Label("Download For this File : " + fileName)); Button button = new Button("Download"); button.addClickHandler(new ClickHandler(){ @Override public void onClick(ClickEvent event) { // i do not know what to do here }); content.add(button); initWidget(content); } } above is a simple widget that will supply a panel that will allow for the download of a file based on a fileName as you can see above, i do not know what to do to be able to download the file is there any one that can point me in the right direction?

  • How to use global view files in Zend Framework?

    - by terrani
    Hi, I am trying to use global or shared view files. Let's say I have a module in Application/Modules/default and I have "IndexController.php" inside "default/controllers" within "IndexController", I would like to render a view that is located in "Application/Views". I tried to use addScriptPath, but Zend_View tries to look "Application/Views/index" directory. How do I eliminate "index" ?
