How do I know that there are double-byte characters in s String?
Hi!
If I have a String that contain English and Chinese words,
How do I know that the String contain double-byte characters(Chinese words)?
Following is my method and the problem I suffered...
String A = "test(double-byte chinese)test";
byte B[] = A.getBytes();
if(A.length() != B.length)
System.out.print("String contains double-byte words");
else
System.out.print("String does not contain double-byte words");
If the String contains Chinese words,then A.length() will be smaller than B.length...
I run the program on Window NT workstation(Tradtional Chinese version) and it works...
Then I run the same program on Redhat 6.0(English version),
but the result was not the same as running on NT...
because A.length() always equal to B.length...
I guess that's because of Charset of OS...
But I don't know how to set the Charset of Linux...
Does anybody have other solution to my problem?
Any suggestion will be very appreciate!
A String is always in Unicode. You cannot see what kind of character is in the string unless you compare with the Unicode range of charcters. E.g. 3400-4DB5 is CJKUnified Ideographs extension A. Then you at least know that is is not Latin-1 or other.

Am trying to update software through "Software Update" on my iMac (latest Lion operating system).
I keep getting message "An error has occurred. The request timed out"
How do I know if there are software dates available to down load.
ErnieTwo things, bushmanernie (love the name)
First what version of Lion are you running and have you downloaded any Combo updates since you installed it.
Second; I see you only have 10.6.2 in your profile. You might like to update it.
I don't have Lion myself but I'm guessing you don't have the very latest version. You can check what should be available through the opening Apple support page > downloads. -
Double byte characters in a String - Help needed
Hi All,
Can anyone tell me how to find the presence of a double byte ( Japanese ) character in a String. I need to check whether the String contains a Japanese character or not. Thanx in advance.

How can i know that servers are up and running?
hello everyone...
i have a distributed application which does the following.. a client submits a job which is passed from one server to another and after some processing on each server the job is returned back to the client.. the thing is that i want to make the whole application more reliable... how can i found out if the next server that i am going to submit the job is up and running?
the client has decided the order of the servers that should be followed but when a server processes the job another one may "die..." and i am telling you that because i cannot check if the cast of the objectReference fails when i make the list on the client...
is there any function that i can call to the orb and find that out ?

I know that there are some clevers guys over this forum..I have a little
question that doesn't refer to Java, But I was quite satisfied with your help that I will try my luck again.
I am writing an application refering to AI field. I need to find a list of last names, computer products and companies as long as I can find for a initial data base to use it.
Where can I find it?
Thank you ,
AmirIf you just want a bunch of data for your app to run over, try census data. I know the U.S. govt has put some of its data on the web. If you want the data in a different language, hopefully a government of a country whose native language you want to write for, has done the same. It seems likely.

Our RS232-enabled instrument sends ASCII strings to COM 1 and I read strings in. For example I get the string "TPM", or at least it looks like "TPM" if I display it. However, if I send that to the selector input of a Case structure, and create a case for "TPM", whether the two appear to match varies. Sometimes it matches, and measuring its length returns 3. Sometimes it measures 7 or 11 or 12 characters long, and it doesn't match. I can reproduce a match or a mismatch by my choice of the command that went to the instrument prior to the command that causes the TPM response, but have made no sense of this clue. I have run it through Trim Whitespace, with Both Ends (the default) explicitly selected. I have also turned the string into a byte array, autoindexed a For loop on that, and only passed the bytes if they don't equal 32, or if they don't equal 0, thinking spaces or nulls might be in there, but no better.
The Trim Whitespace function's Help remarks that it does not remove "double byte characters". But I can't find anything else about "double byte characters". Could this be the problem? Are there functions that can tell whether there are "double byte characters", or convert into or out of them? By "double byte characters", do they just mean Unicode?
Solved!
Go to Solution.Cebailey,
The double byte characters are generally used for characters specific to languages other than English. If you display your message in " '\' Codes Display" in a string indicator do you see any other characters? You could also use Hex Display to see count the number of bytes in the message. You are probably getting messages with non-printable characters that might need to be trimmed before using your application. If you want more information the '\' Codes Display, there's a detailed description found in the LabVIEW Help. You can also find the same information on our website in the LabVIEW Help.

Double byte characters in dataset
Hi Gurus,
I encounter an issue when writing data to dataset with fixed length.
Company Code: US00
Document Number: 1234567890
Fiscal Year: 2014
Line Item: 001 Short Text ( length 10 char): AF 16
Line Item: 002 Short Text ( length 10 char): AF 16
Comment:X
In Unix, it becomes like this:-
US0012345678902014001AF16 X
US0012345678902014001AF 16 X
The X in second line item was not in correct fixed position and cause file being rejected by the receiver system.
I have tried to calculate using the following syntax for AF 16 :
1) strlen(bseg-sgtxt) = 7
2) numofchar(bseg-sgtxt) = 6
I would like to know if there is any idea to resolve the position of subsequent fields after "SGTXT" field if there is double byte characters found. I have tried to pad trailing space but it does not work.
Expected result is where the X of two line items are located at same and fixed position:-
US0012345678902014001AF16 X
US0012345678902014001AF 16 X

Regular Expressions and Double Byte Characters ?
Is it possible to use Java Regular Expressions to parse
a file that will contain double byte characters ?
For example, I want a regular expression to match the following line
tag="double byte stuff" id="double byte stuff"The comments on the bytes/strings were helpful. Thanks.
But I'm still confused as to what matching pattern could be used.
For example a pattern like:
[A-Za-z]
I assume would not match any double byte characters.
I also assume the following won't work either:
[\\p{Alpah}]
because it is posix - US-ASCII only.
So how do you say "match the tag, then take any characters,
double byte, ascii, whatever, then match the text tag - per the
original example ? -
I know that they are now requiring a one time security code. How do I find it? Does anyone know what it is?
There is no such code required to use the Apple TV. A user can setup a passcode to be required for airplay, and Apple ID is required for use of the iTunes store (or any other subscriptions associated with it).

Started a similar string before. When I select a recipient in Messages on my Macbook Pro the name shows up in red and says the recipient is no longer registered on iMessage. I know that they are registered. Is there a problem with Contacts possibly. The previous help has been appreciated but the problem persists.
Hi,
Try iMessaging your own iPhone and see if your account is actually logged in.
It can appear "enabled" and On line but sometimes it is not.
Also try sending from your iPhone (number) to your Apple ID and see if it gets to the Mac.
If it does not use the Sign Out button.
Then shut down the Mac
On restart add back the Apple ID to the iMessages account settings.
I also just checked My wife's iPhone as she popped up red.
It turned out her iPhone did not have Messages On.

When I OCR two versions of the same document and then compare the documents in Acrobat Pro XI, I usually get the message that there are no changes to mark. However, I know there a quite a few number of changes. I raised this question more than a year ago, and the response I received had to do with the quality of the OCR and the scans of the documents. However, if I use Acrobat Pro XI to save the same documents in Word and then run a comparison in Word all of the changes are marked. When a PDF is saved as a Word document in Acrobat Pro XI, is a different OCR module being used than the one used in Acrobat Pro XI for text recognition?
OCR is only for recoginition of the image / picture of text provided by an scanner.
Content typed into a Word file which is converted to a PDF is (in Word and in PDF) *not* an image or picture of text - it is the digital text. So, no OCR involved.
When the "digital" (renderable) text of a PDF's page content is exported to Word no OCR is involved.
When a PDF's content is from the image output of a scanner and this is a picture of text then OCR comes into play.
If this content is exported to Word before doing OCR then it is the image that is exported to the Word file.
Once OCR is performed it is the OCR output that is exported.
OCR output is (always will be) impacted by "the quality of the OCR and the scans of the documents".
Regardless "Compare" is based on a Word file output to PDF1 then edits to the Word file followed by an output to PDF2. You use Acrobat Pro to do a compare of PDF1 & PDF2.
Paper 1 scanned to image 1 to image 1 in PDF1 that gets OCR 1 and
Paper 2 scanned to image 2 to image 2 in PDF2 that gets OCR 2
being processed with Acrobat Pro's Compare can certainly be done.
But - well you've described what can be observed.
