Folders that having non-ascii chars are not displaying on MAC using JFileChooser

On MAC OS X 10.8.2, I have latest Java 1.7.25 installed. When I run my simple java program which allows me to browse the files and folders of my native file system using JFileChooser, It does not show the folders that having non-ascii char in there name. According this link, this bug had been reported for Java 7 update 6. It was fixed in 7 Update 10. But I am getting this issue in Java 1.7.21 and Java 1.7.25.
Sample Code-
{code}
public class Encoding {
public static void main(String[] arg) {
try {
//NOTE : Here at desktop there is a folder DKF}æßj having spacial char in its name. That is not showing in file chooser as well as while is trying to read for FILE type, it is not identify by Dir as well as File - getting File Not Found Exception
UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());
} catch (IllegalAccessException ex) {
Logger.getLogger(Encoding.class.getName()).log(Level.SEVERE, null, ex);
} catch (UnsupportedLookAndFeelException ex) {
Logger.getLogger(Encoding.class.getName()).log(Level.SEVERE, null, ex);
} catch (ClassNotFoundException ex) {
Logger.getLogger(Encoding.class.getName()).log(Level.SEVERE, null, ex);
} catch (InstantiationException ex) {
Logger.getLogger(Encoding.class.getName()).log(Level.SEVERE, null, ex);
JFileChooser chooser = new JFileChooser(".");
chooser.showOpenDialog(null);

Hi,
Did you try this link - osx - File.list() retrieves file names with NON-ASCII characters incorrectly on Mac OS X when using Java 7 from Oracle -…
set the LANG environment variable. It's a GUI application that I want to deploy as an Mac OS X application, and doing so, the LSEnvironment setting
<key>LSEnvironment</key> <dict> <key>LANG</key> <string>en_US.UTF-8</string> </dict>

Non-ASCII chars in applets?

hi,
Spent 4 hours to find a way to use non-ASCII chars in applets (buttons, textareas), but didn't make it.
Simply saying
TextFieldObj.setText("\uxxxx");
//or any equivalent obj. Ex. of \uxxxx: \u015F
doesn't work. I even went into Graphics.paint() example, but it too can paint only ASCII chars.
My hunch is that it is smt. about Character.Subset but i still can't figure out how to do it.
Please SOS,
Reshat.

Hi,
I just managed to get Buttons to show Greek characters, so it appears that static buttons are fine.
However, i still face the same problem for TextField's:
TextFields work fine for IE, but in NN they sometimes convert into ASCII and sometimes give ? The same in HotJava.
So there are 2 questions in my head:
1. why can't NN use the fonts used by IE to display Non-ASCII chars?
2. What is the safest font to use for Non-ASCII chars, to cover the widest possible audience.
P.S. Java solves most cross-platform-browser problems, but the font issue still seems to be dependent on a user and his/her browser. It appears Java is not font-independent in non-ASCII context. If so, it would be nice to develop a plug-in to make sure that if the user doesn't have the font, then a Java-standardized Unicode-based font is used. Otherwise, non-ASCII world is still w/o a real Java.)
Thank you for your feedback,
Reshat.

UploadedFile and filenames with non-ascii chars

Hi
I'm using an UploadedFile object in my web app, and all works fine. However, when I try to upload a file, with a filename containing non-ascii chars (e.g. Spanish), I see that the getBytes method returns an empty byte array, the filename is not stored correctly (the non-ascii chars are lost, replaced by another representation), and that the content-type is application/octet-stream instead of image/png as supposed to be.
If I rename that same file to have only ascii chars - everything is back to normal.
How can I upload files with non-ascii chars in their name?

Hi, back! Spent a few hours experimenting and found
that everything is working great (including the creation
of international non-ASCII foldernames) when I used
utf-8 encoding in the sieve filters rules for the
the match strings and the folder names... at least
so far so good... for your ref and sorry for bothering.

How can I Retrieve special chars from a HTTP Request??

Hi,
I want to retrieve special chars from a request
Chars like accents used in spanish languages or symbols?
Is there any way to do it
Thanks in advance
Alejandro Arredondo

This is my problem
For example:
This is my form:
<form>
<input type="text" name="test">
</form>
I do write a char on the text area. Something like "?" or "?"
or some words with accents
When I retrieve the value with
String value = request.getParameter("test");
and print it
out.println("TEST= " + test);
It prints another symbol that isn't the one I sent in my form.
why?
Thanks

Java 5, Linux, 64-bit: Non-ASCII chars over socket

Hi,
I am having issues with reading non-ASCII chars from a socket. I send a mixed message, with the first part in ASCII and the last bit in non-ASCII. There are no issues with reading the non-ASCII characters on Windows. However, when I try running the server on Linux. The following is a message sample:
Start message<CRLF>
фвафывафвыафыв<CRLF>
The second part (which is encoded in either Windows-1250 or KOI8-R), comes out as 3F (when you look at the bytes) on Linux.
Any suggestions?
Thanks,
Max

You must be using Readers and Writers, and you need to make sure you specify the same charsets when constructing them. Don't leave this to the default, as this seems to vary across platforms and definitely has varied across releases.

IPhone: sectionIndexTitlesForTableView and non-ASCII chars

You specify an array of strings for your section titles in your implementation of UITableViewDataSource method sectionIndexTitlesForTableView. However, it seems like if you have a string with non-ASCII characters, it is left blank (for example the Korean string "누리마루"). Anybody else encounter this issue?

I bump Dr. Chucks thread for a similiar problem with non-ascii chars.
The chars show up but the sorting is a bit off.
Example: A, Å, B, ... Z
Should be: A, B, ... Z, Å, Ä, Ö
In Swedish Å (the letter Aring;) is one of the last letters and should not be placed after A despite being similiar.
Any ideas?

FILE_DATASTORE and non-ASCII chars

I have created an interMedia Text index
with the FILE_DATASTORE option, so that
interMedia treats table entries as
filenames and indexes the corresponding
file on the servers's filesystem.
But whenever the filename contains characters
which are not part of the US7ASCII charset (like dv| _), the file is not found. But both Oracle and the operating system support these characters.
The Oracle instance uses UTF8 as internal
characterset. The client which stores
the filenames in the table uses the
WE8ISO8859P1 charset. The values in the
database table are stored and shown correctly
when viewed with Oracle or Java client
programs.
So where does the charset conversion fail ?
The names are stored correctly, they can be
read correctly by clients, but the indexer
seems to use a wrong charset to translate
the filenames stored in the database into
filenames of the operating system.
Do I have to apply some additonal configurations to my indexer ?

Can Java be started in a directory that contains non ascii char

I installed a product developed using Java in a folder whose name contains non-ascii chars, such as Japanese chars or german chars.
This will cause error said: unable initialise java virtual machine, error code -1
Some one said Java doesn't like being started in a directory that contains non ascii characters. There appears to be no way of passing it unicode parameters.
Is there anyone once hit the similiar issue or know the root cause of such problem?
Thanks

Yes you can use your web start application console. To enter data which is required for your application it is better idea to use java application which runs in console mode althou you may try to run console of windows and then read data from its input stream.

Does Java 5 accept non-ascii chars as identifiers?

I am surprised to find out that Java 5.0 accept non-ascii chars as identifiers.
Is it true that Java 5 really accept non-ascii chars?
Thanks.

Here is the code:

    int ��1 = 1, ��2 = 2;

public static void main(String[] args) {
    ��();

How Aperture encodes non-ascii chars

It looks like Aperture uses a way of encode chars as UTF that seem to be bit unusual, many application (especially web apps) expects another way of encoding Unicode chars. The end result is that non-ascii chars comes out really strange.
When I use applescript to read the IPTC info I need to do something like this before using the data:
set c_title to normalize unicode p_title without decomposition
Is there some way of telling Aperture to do this automatically when exporting photos?
(sorry about the bad use of Unicode terminology but I don't know the area very well)

I've spent quite a bit of time on this topic - I'm the author of Phoshare http://code.google.com/p/phoshare/, an open-source tool to export images and metadata from iPhoto and Aperture. Storing non-ASCII characters in image metadata is a messy business. If you want to get a taste of it, have a look at the Exiftool FAQ at http://www.sno.phy.queensu.ca/~phil/exiftool/faq.html#Q10 . A quote: "Most textual information in EXIF is stored in ASCII format, ... However *it is not uncommon for applications to write UTF‑8 or other encodings where ASCII is expected*". This leads to all sorts of problems, because the reader will have to make assumptions about the encoding used by the writer.
In the case of Aperture, I have found that it writes metadata encoded in a way consistent with what most other applications and on-line services expect. Most of the encoding problems I've debugged where caused by bad input data. E.g. the characters were encoded improperly to begin with, but in a way that they still display as expected in some places (like Aperture). Can you try erasing some of the meta data in Aperture, and retype them from scratch (e.g. not copy-paste, which would paste the same stuff right back). Also make sure that you force-updated the preview images, so that the new meta data get written into the files.

Casting Number as Char - how to hide decimal places?

I am casting a number as a Char because I am concatenating it with other things. The problem is that when I cast to char, it displays two decimal places of just 0's. I really don't want to show the decimal place or anything after it. Is there a way to remove them?
Thanks

Hi,
You can have two approaches for the same.
1> cast( cast(column as int) as char)
2> Go to the column properties(i.e the finger mark on the coulmn heading). Then select the data format tab and check the override the default data format tab. Then you can set the decimal places.

Socket adds junk in place of Ascii chars

hi
I am using socket programming to connect to a device over LAN and write some data on to it. For this i am using some extended ascii characters which constitute the device message formats. But the message received by the device is not as required....some junk characters are coming in place of ASCII chars.
Previously i tested it on the windows, worked fine. But when i put it on linux its giving above mentioned problem.
Any help on this is appreciated.
Thanks
Navin

Are you using bytes or Strings. If you are using Strings, your character encoding may be different on different systems and this can appear as unexpected bytes in your stream.
I would suggest you use bytes and Streams and don't use Strings, characters, or Reader/Writers if you want to introduce your own extended bytes.
Note char is a 16-bit values in Java, unlike byte which are 8-bit.

GSSName is corrupted for non ascii chars

Hi,
I have a setup where a web application is deployed to use SPNEGO for user authentication ( using kerberos V ) and authorization.
We have several users with non english characters in the user ID and even though kerberos authentication succeeds for such users ( KDC / Active Directory is returning valid kerberos ticket which the client embeds in the SPNEGO token). Hoowever, on passing the SPNEGO token to GSS API and extracting the user name from GSS API returns incorrect user name. All non ascii characters in the user name are replaced with some junk byte sequences.
We use JGSS API (with JRE 1.4.08) for extracting the SPNEGO token and create a GSS secruity context object. Later, the GSS Name is extracted from the GSS context object.
Currently I am tesitng the SPNEGo authentication for a user with user ID 123<sp char> . The <sp char> 's unicode value is FE and UTF-8 encoded byte sequence is C3 BE. However, if I invoke 'export' method of the GSSName object and examine the returned byte sequence, instead of C3 BE, the byte sequence EF BF BD EF BF BD is present. The byte sequence for other english characters are proper.
Is this a defect in GSS-API ? Or am I not using GSS properly?
Do I need to have any special setup / configuration for using JGSS with kerberos V for users with non ascii characters in the user ID?
Please advise.
Regards,
Jayaram.

I understand that this is an older thread.
We have spent lot of time on the internet to find out any possible workarounds or permanent solutions to enable Multi-Byte character support for username / password / SPN with Kerberos and Java . But no luck so far :(
Are there any new updates on this i18n issue ?

Problem with ASCII char (127-'\u0080') while printing

Hello,
I am working with socket and want to send some data over the network. I am using Strings for sending data over the socket. In few characters ('\u007F' to '\u009F') I am getting error. Whenever I try to execute this line, I got an error
System.out.println ( '\u0080') -> It is printed as '?' = '\u003F'.
I try to send this character (String) over the network through Client Socket\
Socket ClientSocket = new Socket("192.168.243.10", "6010");out = new PrintWriter(ClientSocket.getOutputStream(), true);
out.println('\u0080') ;
out.close() ;
ClientSocket.close();It is received with same '\u003F' ='?' at the receiving end (192.168.243.10). While rest all characterset is receiving & printing accurately. Any Comments on it?

You are using a Writer to send those chars, which
means it will attempt to encode them into bytes. But
since those bytes you mentioned are not defined in
ASCII (or in UTF-8859-1 for that matter) then the
charset converter encodes them as "?".
Can you explain why you are using Strings when it
appears you need to send untranslated bytes?I am following a pattern of bits to identify data elements present in message string.
I am writing a chat Client & Server. While sending message to chat clients, I need to tell whether private window request, or main channel request or notification (will display in both private window & main window). In this way, I have 32 combination of options that can be present in my message, so I am using 4 chars (32 bits) to figure out which option is present or which message element is present in the received message. So, I am using bitmap pattern to identify data elements in my message. For this I am using bits of a char (lower 8 bits). This will help me in identifying the characters present in the message. I have specific range of characters that aren't interpreted correctly. '\u007F' to '\u009F' while rest are working absolutely fine with me. Why these characters aren't working? This is what I am trying to figure out.
Hope I clarifies the situation.
