How to input extended characters in textfields.
Hi,
I wanted to know how java handles extended characters such as alt130 , alt137 etc... in textfields. Is the only way to input these by alt-codes or is there another way?
Much thanks,
Hugo Hendriks
See this site for full info on Chinese input:

There is no need for a special keyboard for any kind of input.

E61 and extended characters (especially tab key)
I've upgraded to the new firmware and can't figure out any more how to input special characters (the ones not accessible from the special characters pages, that is).
It used to be that I could hit the blue key and then ctrl+ the ascii code of the character to type it in. This no longer works. Is there any way under the new firmware to send the ascii code out?
If not, when I'm in a putty session, I at least need to send out a tab character at times -- is there a way to do this via some key combo I don't know?
Thanks for any help... I'm running with a plain English firmware, no surprises here...Hey nyamada, I found your post in my quest for the same answer.
I've since found the answer myself here:

Hit Ctrl-I for tab auto-completion in Putty. -
I am using the electronic writing pad made by PENPOWER Inc. to input Chinese characters onto my PC programs (e.g. Winword, Internet Explorer, Excel, etc.) But I can not make it happened on Firefox, please advice what I have to do with the configuration of the Firefox or using any other method to make it work. Thanking you guys in advance for helping me to solve this problem.
cor-el,
Thank you very much for your advice. The new software of Penpower works rightaway after I installed it on my pc. Thanks again.
十分感激你的幫忙！ -
Extended characters not getting through VM properly in JDK1.4 versions
This is on WIndows platform with regular US keyboard.
When you type "ALT+0252" (it is �) from your regular (English) keyboard using it's numeric keypad, somewhere in the VM there is translation happening that is converting the numeric value of 252 to 242 and there by displaying the character mapped to ALT+0242 (which is �).
Similarly, every other extended character is getting translated somewhere thereby displaying the wrong character.
The way to look at Character Map on Windows platform is Start|Programs|Accessories|System Tools|Character Map.
Best way to compare what is getting through VM is by running
regular Notepad (Start | Programs | Accessories | Notepad) and typing
above character and then running the Notepad that comes with J2SDK install (java -JAR JDKInstallDir\demo\jfc\Notepad\Notepad.jar) and typing the same character.
You will notice that the regular Notepad displays � when you type ALT+0252 but the java Notepad displays � when you type the same ALT+0252 character.Here is the sample code. You can first run it in jdk1.3 environment and enter the extended characters in the textfield. You will notice that they get rendered correctly (such as ALT+0252 gets rendered as �)
Then try running the same applet in jdk1.4 environment and enter the same extended characters in the textfield and you will notice the difference. ALT+0252 will now get rendered as � which is not correct.
JComponent class in JDK1.4 seems to be translating the string some how before rendering it.
Please let me know if you have any ideas or suggestions on this weird behavior in JDK1.4. Thanks.

How to input data into an arraylist from a text file?
I am trying to take data from a text file and put that data into an arraylist. First here is the text file:
[item1, 10, 125.0, item2, 10, 12.0, item3, 20, 158.0]
3
4530.0
[item5, 65, 555.5, item4, 29, 689.0]
2
56088.5
[item7, 84, 34.5, item6, 103, 0.5, item8, 85, 1.36]
3
3065.1The text between the [ ] is the output from my arraylists. I have three arraylists. The first [ ] belongs to arraylist A, the second to arraylist B, and the third to arraylist C. The format of the arraylists is this:
<item name>,<# in stock>,<value of one item>
The first number below the arraylists in the text file represents the number of items in the list. The second number below the arraylists represents the total value of the items in the arraylists.
Here is the class file I have (yes, it does everything):

How to display cyrillic characters in a PDF
I am fairly green in terms of representing text in PDF documents and need some assistance. My main question is how do I represent Cyrillic characters in PDF files.
I know the basics of how to represent text in PDF files and the PostScript commands to use. I know that bytes written to the file in the range of 0 to 255 will print correctly when using the correct encoding (we are using the WinAnsiEncoding). What I cannot seem to figure out is how to represent extended character sets and different glyphs (such as those used in the Cyrillic alphabet) in a PDF file. Do I need to use CID fonts and CMaps?
Here is an example of the text I understand how to print:
stream
0.00000000 0.00000000 0.00000000 RG
0.00000000 0.00000000 0.00000000 rg
BT
/Helvetica 14 Tf
7.2 768.96 Td
(Hello World!) Tj
ET
endstream
I'm really not clear on how to represent any of the Chinese or Japanese fonts either, so really any help here is appreciated. Any examples are appreciated as well.
Thanks!You don't need to use CIDFonts and CMaps for Cyrillic (though you can). The crucial thing to realise is that displaying Latin1 (that is, English and related text) leaves you in a very simple corner of PDF. Doing anything with other encodings instantly makes a project more complex, perhaps 10 times more complex. Far eastern fonts perhaps 10 times more complex again.
The principle is the same for all of them. To use any character you need
1. A font containing that character. PDF has built in fonts containing Latin1, such as Helvetica, but there is no such luxury for other encodings.
2. The right (license) to embed the font.
3. The technical ability to embed the font. In many case this isn't just a case of embedding a file as a stream, but also you need to analyse the tables in the font, and sometimes trim or modify them.
4. An encoding for the font.
5. Text streams which use character positions in the encoding to show the text.
Basically you need to read and read and reread the chapter on text, and its references (such as font formats). This will become your constant friend or tormenter for the many months of the project.
If you don't like the sound of that, or it doesn't make ecomomic sense to do that, there are many PDF libraries which have taken the necessary months or years to do this. -

How to display unicode characters
hi
How could we save, display, write or read Unicode characters.Thanks a lot. I fully understand what you have said.
My test is running under Traditional Chinese "Big5" Windows XP system.
Chinese "Big5" font can display on a Console window. I can even input Chinese into the console window.
Or, in another word, I can TYPE a text file which contains "Big5" Chinese characters and show from the Console window. I assume this will prove that the Console window do know how to handle Chinese characters.
Now, my test is trying to CONVERT a Unicode string into a Chinese character string expecting the resulting Chinese string can be output into the Console window and let the XP Console window to handle the Chinese character display.
My main concerned question is "How can I CONVERT a Unicode string into a Big5 Chinese character string?"
String tstr = new String("\u39321\u28207","big5");
It seems this statement is INCORRECT, isn't it? -
As a recentish switcher I'm completely stumped by how I can enter extended characters. I need to enter the character code 0239 to get a special character in a font I'm using. On a PC I'd simply type 0239 on the numeric pad while holding down the Alt key. But that doesn't work on the Mac.
Any help much appreciated. GeoffT.Most apps have an item in the "Edit" menu called "Special Characters..." which brings up a palette with just about every conceivable character set you could want. That should do the trick, unless the app is so old that it doesn't enable this system-level item. Assuming it works, once you've found the character you want, just click the "Insert" button in the lower-right of the palette to insert it into the active text field.
Here's Apple's description of the same feature:
http://docs.info.apple.com/article.html?path=Mac/10.5/en/8164.html
There are also many longstanding tricks to enter the more common special characters such as curly quotes, emdashes, and accented characters. Here's a very old but still valid cheat sheet:

JTidy with extended characters?
Hi all,
I've been using JTidy to tidy up html to valid xml, and it works fine, except when I have extended characters in the HTML.
Has anybody else come across this problem? Is there any solution? JTidy doesn't look like its had any releases since 2001. Is there any other active projects that do the same thing?
thanks,
JustinJust looking at the input, and all extended characters are entities.
So the input is:
<html>
<head>
</head>
<body>
ýÿăĈ
</body>
</html>and the output is:
<html>
<head>
<meta name="generator" content="HTML Tidy, see www.w3.org" />
<title></title>
</head>
<body>
��[][]
</body>
</html>where the "[]" characters represent a box. I.e. a character System.out.println can't render.
If I look at the integer value of them, they are 3 & 8.
So I guess I'm trying to turn off the entity replacement in the JTidy. Is this possible?
thanks,

Error with extended characters
hi i have a problem with extended characters and it only happens when i have an attachment with the mail
MimeBodyPart bp = new MimeBodyPart();
String content = "� � � � � � � � � � � � �� � � � � � � � � � � � �";
bp.setContent( content, "text/plain; charset=UTF-8" );
mp.addBodyPart( bp );
//code for adding a attachment is added to the mp using MimeBodyPart
msg.setContent( mp ); // add Multipart
msg.saveChanges(); // generate appropriate headers
ByteArrayOutputStream baos = new ByteArrayOutputStream();
msg.writeTo( baos );msg is a MimeMessage.
Now this msg is stored in a cache and later retrieved using
String s = "";
java.lang.Object o = msg.getContent();
if ( o instanceof String )
s = (String) o;
else if ( o instanceof Multipart )
try
Multipart mp = (Multipart) o;
MimeBodyPart bp = (MimeBodyPart) mp.getBodyPart( 0 );
s = (String) bp.getContent();
catch ( Exception e )
cLog.error(e.getMessage(),e);
}now s contains "�€ �� �‚ �ƒ �„ �… �† �‡ �ˆ �‰ �Š �‹ �Œ �� �� �� �� �� �� �� �� �� �� �� �� ��" which is wrong.
This has been bugging me for a couple of days now.
could anyone please give a solution.
Many Thanks in advanceUsing these literal non-ASCII characters in the string constant might
look great in your editor but might not be giving the correct Unicode
values. Try replacing the special characters with Unicode escapes
(\u####).
If that doesn't work, step through the original string and print out
each character as an integer. Then do the same for the string you
fetch from the message. Compare the integer values. If they're
not the same, post the details. If they are the same, the problem
is most likely in how you're displaying the characters you read
from the message. -
I previously used Dreamweaver 4 without CSS and then moved onto Dreamweaver 8, again without CSS. I am trialing Dreaweaver CS5 and have updated my site content to <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> from just <HTML>
Extended characters such as e acute which used to appear correctly in earlier versions of Dreamweaver, although they appear correctly in Dreamweaver Live View now appear rather differently in Internet Explorer 8 e.g an e acute appears as A with a tilda followed by a copyright symbol. How can I correct this please?Thanks John,
Since reading your message I discovered that the error occured only where I had copied text with extended characters from another website and pasted it into mine.
Best wishes,

How to get value of a textfield which has been set as Renderd false.
Hi all
how to get value of a TEXTFIELD which has been set as Renderd false.
i am getting the value of this textfield from an lov but dont want to show it to the user.
getting error as:
attribute xxxx required for view object yyyyy.
pls help
naveenYou can create item inside your LOV region, set the item style to formValue. You can associate this to a View Object field. It can also act as mirror of any other text input field.
FormValue can hold the value and will not be diaplyed to user. You can read value from it controller
example
OAFormValueBean orgValue = (OAFormValueBean)webBean.findChildRecursive("OrgIdFormVal");
Or you can read it fro the VO associated with this form value.
