Convertion of byte array in UTF-8 to GSM character set.

I want to convert byte array in UTF-8 to GSM character set. Please advice How can I do that?

String s = new String(byteArrayInUTF8,"utf-8");This will convert your byte array to a Java UNICODE UTF-16 encoded String on the assumption that the byte array represents characters encoded as utf-8.
I don't understand what GSM characters are so someone else will have to help you with the second part.

  • Truncate byte array of UTF-8 characters without corrupting the data?

    Hi all,
    I need to be able to determine if the byte array, which is truncated from the original byte array representing UTF-8 string, contains corrupted character. Knowing if the byte array contains corrupted character allows me to remove it from the truncated array.
    As in the sample code below, when truncate the string with 16 bytes it displays ok. However, truncate with 17 bytes, the last character is corrupted. Is there a way to check to see if the character is corrupted so that it can be removed from the truncated byte array?
    Thanks in advance,
    Phuong
    PS: The Japanese characters I chose it randomly from Unicode charts. I don't know their meaning so if it is offensive, please forgive me.

    Since the byte array is in UTF-8, you can easily examine whether it is corrupt or not by taking a look at the last 4 bytes (at most). That is because the bit distribution of each byte (1st, 2nd, 3rd, and 4th) in UTF-8 encoding is well defined in its spec.
    BTW, a Japanese Hiragana/Kanji character typically has 3 bytes in UTF-8, so truncating with neither 16 nor 17 bytes would produce correct truncation.

  • Converting a byte array into int

    Here's my problem, I've read my data from a server into a byte array.
    the array is 12 elements in length representing three int variables.
    int flag;
    int query_a;
    int query_b;
    here's what i receive:
    0 0 0 0 34 0 0 -2 21 0 0 0
    how do i convert these into the int values i need.
    i know the first four are for flag = 0, but how does it convert?
    0000 = 0 for each byte
    00000000 00000000 00000000 00000000 = 0 for each bit?
    or is there a method to convert from a byte to int?

    Look at the ByteBuffer class (part of 1.4.1) - before that, you would have had to manually build your integers using left shift and & operator (not that big of a deal, really).
    Be sure you know the "Endian"-ness of the platform you are reading data from though, otherwise, your ints will not be what you expect!

  • UTF-8 or Windows character set?

    I'm putting through RH7 several projects previously produced
    in RH5x and RH 6. (Not the WebHelp output, but copies of the
    original source projects, launched with RH 7.)
    Special characters are a problem. I plan to do some testing.
    Maybe it's not the fault of RH, and I need to update my source
    files manually for these characters.
    But meanwhile, I thought I'd ask these questions:
    1. Is there a reason to choose UTF-8 for Windows users? Will
    IE and other browsers display UTF-8 correctly in a Windows
    environment?
    2. If UTF-8 is OK, is there a reason not to choose UTF-8 for
    a project previously worked in RH 6 or earlier? I expect RH 7 to
    produce the correct output, but it is having a problem with older
    special characters in the source files. The corollary question is
    whether RH 7 recognizes and converts outdated code for special
    characters when they occur in imported html (source project) files.
    Thanks.

    It sounds like your problem is with fonts being replaced. You should start by opening your fontbook application and looking for 1 fonts to disable which will more than likely solve your problem.
    Disable this font:

  • Reading in any file and converting to a byte array

    Okay what I am trying to do is to write a program that will read in any file and convert it into a int array so that I can then manipulate the values of the int array and then re-write the file. Once I get the file into an int array I want to try and compress the data with my own algorithm as well as try to write my own encryption algorithm.
    What I have been looking for is code samples that essentially read in the file as a byte array and then I have been trying to convert that byte array into an int array which I could then manipulate. So does anyone have any sample code that essentially takes a file and converts it into an int array and then converts it back into a byte array and write the file. I have found code that is close but I guess I am just too new to this. Any help would be appreciated.

    You can read a whole file into a byte array like this:File f = new File("somefile");
    int size = (int) f.length();
    byte[] contents = new byte[size];
    DataInputStream in = new DataInputStream(
                              new BufferedInputStream(new FileInputStream(f)));
    in.readFully(contents);
    in.close();Note that you need to add in the proper exception handling code. You could also use RandomAccessFile instead of the DataInputStream.
    Writing a byte array to a file is easier; just construct the FileOutputStream, call write on it with the byte array, and close the stream.

  • Converting Image to Byte Array and then to String

    Hi All...
    Can anyone please help me. I have got a problem while converting a Byte array of BufferedImage to String.
    This is my code, First i convert a BufferedImage to a byte array using ImageIO.wirte
    public String dirName="C:\\image";
    ByteArrayOutputStream baos=new ByteArrayOutputStream(1000);
    BufferedImage img=ImageIO.read(new File(dirName,"red.jpg"));
    ImageIO.write(img, "jpg", baos);
    baos.flush();
    byte[] resultimage=baos.toByteArray();
    baos.close();
    Then i tried to convert this byte array to a string
    String str=new String(resultimage);
    byte[] b=str.getBytes();
    This much worked fine. But when i reversed this process to re-create the image from that string. i found the image distroted.
    BufferedImage imag=ImageIO.read(new ByteArrayInputStream(b));
    ImageIO.write(imag, "jpg", new File(dirName,"snap.jpg"));
    I got this snap.jpg as distroted.
    Please help me i have to convert the image to a string and again i have to re-create the image from that string.

    To conver the bytearray to string use base64.encoding
    String base64String= Base64.encode(baos.toByteArray());
    To convert back use Base64.decode;
    byte[] bytearray = Base64.decode(base64String);
    BufferedImage imag=ImageIO.read(bytearray);

    I am reading an image from a file into a BuffertedImage then writing it out again into an array of bytes which I store and use later on in the program. Currently Im doing this in two stages is there a way to do it it one go to speed things up.

                //Write Buffered Image to Byte ArrayOutput Stream
                if (bi != null)
                    //Convert to byte array
                    final ByteArrayOutputStream output = new ByteArrayOutputStream();
                    //Try and find corresponding writer for reader but if not possible
                    //we use JPG (which is always installed) instead.
                    final ImageWriter iw = ImageIO.getImageWriter(ir);
                    if (iw != null)
                        if (ImageIO.write(bi, ir.getFormatName(), new DataOutputStream(output)) == false)
                            MainWindow.logger.warning("Unable to Write Image");
                    else

                            MainWindow.logger.warning("Warning Unable to Write Image as JPEG");
                    //Add to image list
                    final byte[] imageData = output.toByteArray();
                    Images.addImage(imageData);
                  

    If you don't need to manipulate the image in any way I would suggest you just read the image file directly into a byte array (without ImageReader) and then create the BufferedImage from that byte array.

  • Byte array to base64encoder problem, cannot encode a 7.7 MB file

    hey guys, so ive been trying to use the base64encoder to encode a bytearray which is then sent thru a webservice to the server to be decoded.
    and as the subject of this post suggests, i have been having problems encoding a big file,
    forexample i tried to upload/convert a 84KB image and it worked just fine... the trace of the string ended with a "==" which i believe means that the conversion is complete...
    but when i try to upload a 7.7MB image, it is, i guess, crashing... i dont see any "==" in the string... so i guess its not working... i was wondering if there is any any type of file size limit or soemthign for the encoding...

  • Byte Array from SQL Reporting Service

    I am calling the Render method of the Microsoft SQL Reporting
    Service's ReportExecution web service. It returns a Byte array in
    the lastResult object. I am having the hardest time figuring out a
    way to convert that byte array into something I can use in Flex.
    The byte array, once converted into a more user friendly format,
    will contain the rendered version of a SQL Report in whatever
    format I have specified...in this case it is XML. Any input or
    suggestions would be appreciated.

    This is a little late, I know. but I just spent the day
    struggling with this very issue. Hopefully this can help someone
    else in the future. Here's my solution...
    on MX:Operation -- result="fillXML()"
    then
    private function fillXML(): void {
    var x:XML = new
    XML(wsProps.GetDatasetData.lastResult.toString());
    ...do what you need with your xml...
    I use an XMLList node of the result as the source property
    for an XMLListCollection bound to a datagrid. Let me know if you
    need more help to get it working. It works like a charm now that I
    figured that out. I don't know if it's a slimy hack, or not, but it
    gets the job done.

  • How to create PNG file from byte array of RGB value?

    Hi
    Here is my problem.
    I have drawn some sketchs (through code in runtime) on canvas. I have grabbed the RGB information for the drwan image and converted to byte array.
    I have to pass this byte array to server and generate a png file and save.
    Please help.

  • Converting a byte[] back to key problem

    I CAN create a key and convert the key to a byte array, then convert the array to a string(base 64):
    KeyGenerator generator = KeyGenerator.getInstance("DES");
    generator.init(new SecureRandom());
    key = generator.generateKey();
    byte[] keyBytes = key.getEncoded;
    BASE64Encoder encoder = new BASE64Encoder();
    String randomKey = encoder.encode(keyBytes);
    and I CAN save that string to a database, forget about it, then sometime later reload it and convert it to a byte array again:
    String loadedKey = "WhAt3Ver-It-I5" //from DB
    BASE64Decoder decoder = new BASE64Decoder();
    byte[] loadedKeyBytes = decoder.decodeBuffer(loadedKey);
    what I CAN'T do is convert the loadedKeyBytes back into the key of the same type as it was originally, enabling me to decrypt whatever that key originally encrypted.
    Does anyone know.
    I know I need to convert it to a KeySpec, I presume as:
    DESKeySpec keySpec = new DESKeySpec(loadedKeyBytes);
    this compiles correctly.... but how do i then recreate the key so i can use it for decryption.
    Once i've finished this test program I should be able to port it to my application.
    Many thanks in advance guys!
    Cheers!

    You need to use a SecretKeyFactory to convert the byte array back to a SecretKey to use in decryption. Continuing your example:
    SecretKeyFactory skf = SecretKeyFactory.getInstance("DES");
    DESKeySpec desKeySpec = new DESKeySpec(loadedKeyBytes);
    SecretKey sk = skf.generateSecret(desKeySpec);
    Use sk in the call to the Cipher init() function. (Note that you don't call KeyGenerator to restore a key from its bytes.)
    Incidently, if you're using ECB mode for encryption I don't think you need to worry about the Initialization Vector. However, if you're using CBC mode (which is the default DES mode for the default SunJCE provider), I believe you also have to make sure that the decryption system starts from the same Initialization Vector that was used for encryption. To deal with this, if 'cipher' is your encryption Cipher object, then you call
    byte bytIV[] = cipher.getIV();
    to get the 8-byte IV array. To decrypt, you need to call:
    IvParameterSpec iv = new IvParameterSpec(bytIV);
    This is an AlgorithmParameterSpec, and can be used as the third argument to the init() function for Cipher to set up decryption, e.g.
    Cipher cd = Cipher.getInstance("DES/ECB/PKCS5Padding");
    cd.init(Cipher.DECRYPT_MODE, sk, iv);
    I believe that CBC mode is more secure than ECB mode when you have more than 8 bytes of material to encode (e.g. use "DES/CBC/PKCS5Padding"
    when you create the Cipher objects).
    To simplify things a bit, you might just want to use a fixed 8-byte Initialization Vector by constructing a IvParameterSpec and using it for all DES encryption and decryption.
    The documentation on all of this is extraodinarily obscure.

  • Make sound file from byte array?

    Ok say I have a program that gets a byte array from a sound file and then randomly removes some of the samples from the array, so that instead of having a value the bytes are just zeroes. I then want to play my new byte array. Here is the code I try to use but when I use it nothing happens.
    AudioFormat = ((AudioInputStream) AudioSystem.getAudioInputStream(**The Original Sound File**)).getFormat();
    int numBytesRead = 0;
    DataLine.Info dataLineInfo = new DataLine.Info(SourceDataLine.class, audioFormat);
    SourceDataLine sourceDataLineTemp = (SourceDataLine)AudioSystem.getLine(dataLineInfo);
    sourceDataLineTemp.write(audioArray, 0, audioArray.length);(Try..catch removed for clarity.)
    Also, is it possible to convert a byte array to a .wav sound file?

    Im pretty sure if you just write that byte array to disk and open it as a wav file that will do the trick, because thats all a wav file is anyways, a stream of bytes representing audio

  • Confusion regarding Binary data and byte arrays

    HI guys,
    I have a question...i am going to send some binary data...the format of that data is that first two bytes is the lenght of the data and then follows that data. Here i have one confusion. e.g. i want to say that the lenght of my data is 1000 bytes. How do i do it.
    coz if i do something like this.
    int k = 1000;//the length of my data
    String binaryString = Integer.toBinaryString(k);
    byte[] binaryData = binaryString.getBytes();
    and then if i say binaryData.lenght, i see a lenght of 10, as the binary string which
    is generated is -> 1111101000. i guess its obivious as this byte array is nothing but perhaps a character array with each character occupying one thread...so what exactly is the difference between byte array and binary data. and in the above said condition how do i send the binary data?
    Also adding to my confusion is the fact that i have a file which contains binary data, but that data is not 10010101 type of data...its just some absurd characters. How do we explain this.
    i would be highly grateful if you could explain me the solution to this problem.
    I am not getting as to how to go about it.
    its urgent..pls help...

    one sec..actually i dont want to 'read' the two bytes. That i know how to do? but The thing is that i want to write a binary stream. right? so in that the first two bytes should be the size of the data, followed by the data itself. So i want to write the first two bytes, which should contain the size of data (as a matter of fact i have that binary data in a byte array). But my question is , that if i say the size of data is 1000 (bytes , since, as i said i am gettting the data as a byte array), how do i write this in my binary stream as 1000 in this case would be an int. right? which is four bytes. So essentially that byte array (which contains binary data) i have to forward to somewhere, say X , but X reads binary data in the following way...it expects the first two bytes to give him info regarding the size of the data to follow and then it starts reading the data from the third byte onwards till the size of the data (which it got by reading first two bytes)...i hope i could communicate my confusion better this time
