Hi Everybody,
I am Hemant Shukla working as Sr.Oracle Consultant in
Singapore.I am facing a problem with oracle Double
-Byte Conversion.My Software is in Oracle-9i and
D2K-6i.My client requirement is to convert the whole
software in Chinese language .At the same time he can
look for english language also ....Then Malayisan then
Thai...I tried my hand going into registry Editor
Changing NLS_LANG into chinese with UTF-8.But can't
get through it.Please give me solution.
Thanks & Regards

Hemant,
> But can't get through it.
What's your problem exactly? Are you getting errors for something else? What's the value of NLS_LANG you tried?

Encoded double byte characters string conversion

I have double byte encoded strings stored in a properties file. A sample of such string below (I think it is japanese):
\u30fc\u30af\u306e\u30a2
I am supposed to read it from file, convert it to actual string and use them on UI. I am not able to figure how to do the conversion -- the string contains text as is, char backslash, char u, and so on. How to convert it to correct text (either using ai::UnicodeString or otherwise)?
Thanks.

Where did this file come from? Some kind of Java or Ruby export? I don't think AI has anything in its SDK that would natively read that. You could just parse the string, looking for \u[4 characters]. I believe if you created a QChar and initialized it with the integer value of the four-character hex string, it would properly create the character.

How do I convert a double-byte encoded file to single-byte ASCII?

Hello,
I am working with XML files (apparently coded in UTF-8) which encoded in double-byte characters.
The problem is the characters for end of line: 00 0D 00 0A
This double byte end of line is causing a problem with a legacy conversion tool (which deals with 0D 0A). The file itself contains no
accented/international characters, so in principle converting to single-byte should not cause any problems.
I have tried to convert this file with tools like native2ascii and the conversion tools that are part of Notepad++ but without
any luck - the "00 0D 00 0A" are still present in the output
Can anyone point me to a tool or some code that can convet this file into single-byte?
Thank you.

Amiens wrote:
native2ascii.exe -encoding UTF-16 -reverse INPUT.xml OUTPUT.xml
gives 00 00 0 0D 00 00 00 0A
so clearly that is not the required output.What you've got there is UTF-16 encoded text that's been converted to UTF-16. Get rid of the "-reverse" option and you should see the result you expect.

Text strings from VISA read don't match identical looking text constants - could it be double byte characters"

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.

Using Double Byte Characters in URL For Session Variables

When I supply the value for a session variable in the URL for an IRPT page where the value contains double byte characters, Japanese in this case, the characters are corrupted by the time they are entered for the session variables. Does anyone know a solution to this problem or experience in this area? Currently using xMII 11.5 SR3.

Hi Bryan,
I would suspect that under the covers the session variable is of datatype string. For double byte characters, it would need to be wstring. There is a better explanation to be found at:
Link: [Kanji and Java Datatypes|http://www.unix.com.ua/orelly/java-ent/jenut/ch10_04.htm] or you can try google on Kanji Datatype OR Kanji Java Datatype
It could also be a problem with the operating system which I ran into about 10 years ago, but I would hope that Microsoft had moved beyond that by now.
Maybe some more technical folks could chime in to confirm or deny my explanation.

Crystal XI R2 exporting issues with double-byte character sets

NOTE: I have also posted this in the Business Objects General section with no resolution, so I figured I would try this forum as well.
We are using Crystal Reports XI Release 2 (version 11.5.0.313).
We have an application that can be run using multiple cultures/languages, chosen at login time. We have discovered an issue when exporting a Crystal report from our application while using a double-byte character set (Korean, Japanese).
The original text when viewed through our application in the Crystal preview window looks correct:
性能著概要
When exported to Microsoft Word, it also looks correct. However, when we export to PDF or even RPT, the characters are not being converted. The double-byte characters are rendered as boxes instead. It seems that the PDF and RPT exports are somehow not making use of the linked fonts Windows provides for double-byte character sets. This same behavior is exhibited when exporting a PDF from the Crystal report designer environment. We are using Tahoma, a TrueType font, in our report.
I did discover some new behavior that may or may not have any bearing on this issue. When a text field containing double-byte characters is just sitting on the report in the report designer, the box characters are displayed where the Korean characters should be. However, when I double click on the text field to edit the text, the Korean characters suddenly appear, replacing the boxes. And when I exit edit mode of the text field, the boxes are back. And they remain this way when exported, whether from inside the design environment or outside it.
Has anyone seen this behavior? Is SAP/Business Objects/Crystal aware of this? Is there a fix available? Any insights would be welcomed.
Thanks,
Jeff

Hi Jef
I searched on the forums and got the following information:
1) If font linking is enabled on your device, you can examine the registry by enumerating the subkeys of the registry key at HKEY_LOCAL_MACHINEu2013\SOFTWARE\Microsoft\Windows NT\CurrentVersion\FontLink\SystemLink to determine the mappings of linked fonts to base fonts. You can add links by using Regedit to create additional subkeys. Once you have located the registry key that has just been mentioned, from the Edit menu, Highlight the font face name of the font you want to link to and then from the Edit menu, click Modify. On a new line in the dialog field "Value data" of the Edit Multi-String dialog box, enter "path and file to link to," "face name of the font to link".u201D
2) "Fonts in general, especially TrueType and OpenType, are u201CUnicodeu201D.
Since you are using a 'true type' font, it may be an Unicode type already.However,if Bud's suggestion works then nothing better than that.
Also, could you please check the output from crystal designer with different version of pdf than the current one?
Meanwhile, I will look out for any additional/suitable information on this issue.

Invoke-WebRequest - Double byte characters issue in windows 8.1

I try write a powershell script to download a file from web server but failed. The path have double byte characters.
I could run in Windows server 2012 and 2012 R2 successfully, but fail in Windows 8 & 8.1
Do there any difference below Windows server and client powershell?
Region and setting are same in Windows 2012 & Windows 8
Script as below
Invoke-WebRequest -Uri " http://hostname/m/%E9%...../......./...../xxx.jpg"

Security settings are one possible cause of this.
Since we don't have your URL we cannot reproduce this.
It is "different". Using "difference" had me confused for qa bit. I though you were trying to figure out the difference between two things.
Use:
$wc=New-Object System.Net.WebClient
$ws.DownloadFile($url,'c:\file.jpg')
You will see less issues and it is faster.

Given filename or path contains Unicode or double-byte characters.Retry using ASCII characters for filename and path What does this mean? it happen when I publish an OAM

Given file name or path contains Unicode or double-byte characters. Retry using ASCII characters for filename and path
What does this mean? It is happening when I try to publish an OAM for Dreamweaver.
Also: How can I specify the browser in Edge Animate? It is just going wherever. Are there no Preferences for Edge Animate?
BTW. Just call it Edge. Seriously. Do you call it Illustrator Draw? Photoshop Retouching?

No, my file name is mainContent.oam
My project name is mainContent.an
This error happens when I try to import into Dreamweaver. Sorry, I wasn't clear on that earlier.
I thought maybe it was because I had saved my image as a png. So re-saved as a svg, still get the error.
DO I have a setting is Dreamweaver CC that is wrong? Should I try this in Dreamweaver CS6? I might try that next.
Why is this program so difficult? I know Flash. I know After Effects. I can work the timeline part just great. It's always in the export that I have problems.
On a MacPro, 10.7.
Are you an Adobe person or just a nice helper?

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 ?

Report in PDF format can not support double byte character ?

Hi :
I am developing the simplified chinese application , when i generate the report in PDF format , i found all double byte character did not display correctly . i am using dev6i+patch5 , why ?
it is a bug of form or not ???????
HELP !!!

try this ,Install acrobat4.0 or above and make sure you got acrobat distiller which will add a acrobat distiller printer in you windows. print report direct to that printer (don't change desformat) and you should got your PDF file with correct font setting.

JSF and Double Byte Character

Hi,
I wanted to know how to handle <h:outputText> with chinese character or double byte character.
See sample code below :
<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<h:form styleClass="form" id="form1">
<% request.setCharacterEncoding("UTF-8"); %>
<h:inputText styleClass="inputText" id="text1"></h:inputText>
<hx:commandExButton type="submit" value="Submit" styleClass="commandExButton" id="button1" action="#{pc_SubmitTest.doButton1Action}"></hx:commandExButton>
<h:outputText styleClass="outputText" id="text2"></h:outputText>
</h:form>
When you input with double byte character and submit,
the output screen value did not render properly .
I tried this similiar code at JSP, it work fine.
Anybody know how to solve this problem ?
Anything need to do at pagecode level ?
Thank you.

To read Double Byte Character

Hello All,
What is meant by Double Byte Character.
I want to read the this Double Byte Character.Is there any function module or class to read this or any other way to get the double byte character.
This is very urgent please i will reward points.
Thanks,
Karan

Hello Indrakaran,
For to determine Field Properties in Unicode please take a look at the New Unicode Class CL_ABAP_CHAR_UTILITIES.
CHARSIZE attributes:
The CHARSIZE attribute declares the length of a C(1) field in bytes - that is, one byte in NUS, and either two or four in US, UTF-8 or UTF-16 respectively.
Hope it helps,

PDF acceleration F5 BigIP WA and double byte characters

We have been trying to use the F5 appliance from BigIP to accelerate the delivery of PDF files from SharePoint over the WAN. However, we encountered problems with the double-byte files many months ago and have been trying to resolve the problem with F5. We have turned off PDF acceleration on the F5 because of the problems. The problem occurs when PDF files have Kanji characters in the file name. If the file names are English (single byte) the problem does not occur, even if the content of the PDF contains Kanji characters.
After many months of working with F5, they are now saying that the problem is with the Adobe plug-in to Internet Explorer. Specifically they say:
The issue is a result of Adobe's (not F5's) handling of the linearization request of PDF’s with the Japanese character set over 300 KB when the Web Accelerator is enabled on the BigIP (F5) appliance. We assume the issue exists for all double-byte languages, not only Japanese. If a non-double byte character set is used, this works fine. “Linearization” is a feature which allows the Adobe web plug-in to start displaying the PDF file while it is still being downloaded in the background.
The F5 case number is available to anybody from Adobe if interested.
The F5 product management and the F5 Adobe relationship manager have been made aware of this and will bring this issue up to Adobe. But this is as far as F5 is willing to pursue as a resolution. F5 consider this an Adobe issue, not a F5 issue.
Anybody know if this is truly a bug with the PDF browser plug-in? Anybody else experienced this?

Your searches should have also come up with the fact that CR XI R2 is not supported in .NET 2008. Only CR 2008 (12.x) and Crystal Reports Basic for Visual Studio 2008 (10.5) are supported in .NET 2008. I realize this is not good news given the release time line, but support or non support of cr xi r2 in .net 2008 is well documented - from [Supported Platforms|https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/7081b21c-911e-2b10-678e-fe062159b453

Double byte file name in KM NW04

Prior to NetWeaver 04 using the HTML editor, we could name a file in a double byte language (Simplified/Traditional Chinese) by entering the English name in the "ID" field and then entering the double byte name in the "Name" field using "File/Details". While this was not elegant, it worked and would allow users to see the double byte name. Now in NetWeaver 04 we receive the error message "! name is not a canonical name" . Is there a way to name files in double byte using HTML or TEXT editors so our users can see the double byte name?

Hi Boris,
I'm working with Rick on the issue.
I've tried the following (per OSS Note 507624), but we still get the "name is not canonical name" error.
Added the following parameters via configtool to server instances:
-Dhtmlb.useUTF8=X
-Dfile.encoding=UTF8
Added the following parameters via configtool to server instances:
-Dhtmlb.useUTF8=X
-Dfile.encoding=ISO-8859-1
Set the following on <sid>adm account before starting portal (in combination with parameter settings above):
setenv LC_ALL en_US.UTF-8
     locale
     LANG=en_US.UTF-8
     LC_CTYPE="en_US.UTF-8"
     LC_NUMERIC="en_US.UTF-8"
     LC_TIME="en_US.UTF-8"
     LC_COLLATE="en_US.UTF-8"
     LC_MONETARY="en_US.UTF-8"
     LC_MESSAGES="en_US.UTF-8"
     LC_ALL=en_US.UTF-8
Unfortunately, these have not corrected the issue.
Have I misinterpreted the recommendations in the Note or is there something else I needed to do?
Thanks,
Fred Bennett
