Cannot Input and Display Chinese Characters by using ODBC Applications

Dear all,
I am trying to input the Simplified Chinese Characters in the Oracle Database Ver 9.2 running on a UNIX AIX server. The client application we are using is th MS Access 2003 running on a MS Windows XP English version SP 2 without multi-language pack. MS Office 2003 is also an English version.
Database setting is:
NLS_CHARACTERSET=US7ASCII
NLS_NCHAR_CHARACTERSET=AL16UTF16
The Oracle Client used is also ver 9.2 with the ODBC driver ver 9.2. I have tried the following NLS_LANG settings by chaging the registry without any NLS_LANG environment settings:
AMERICAN_AMERICA.ZHT16MSWIN950
AMERICAN_AMERICA.ZHS16GBK
AMERICAN_AMERICA.ZHT16HKSCS
AMERICAN_AMERICA.AL32UTF8
I have tied to load some Chinese Characters in by sqlload and by using the NLS_LANG AMERICAN_AMERICA.ZHT16MSWIN950, AMERICAN_AMERICA.ZHS16GBK and AMERICAN_AMERICA.ZHT16HKSCS, they can be display perfectly in SQLPLUS. But when using the same NLS_LANGs and display in the ACCESS, only ???? are displayed.
When I tried to insert Chinese in ACCESS, the character changed to ???? again. No matter what Chinese characters I inserted by MS ACCESS, the ???? code can be dump with the binary code "03, 0f".
Are there any methods or settings I need to change to make ACCESS an application for inserting and displaying Chinese characters from the Oracle database?
I have tried to set the Non-Unicode setting in the Windows Locale setting:
Chinese (Taiwan) (With AMERICAN_AMERICA.ZHT16MSWIN950),
Chinese (Hong Kong S.A.R) (with AMERICAN_AMERICA.ZHT16HKSCS) and
Chinese (PRC) (with AMERICAN_AMERICA.ZHS16GBK)
when inserting the Chinese Characters by Access. But they all failed with ???? inserted in the DB.
Please kindly advise what should be done.
Thanks.

Are you trying to store the character data in char/varchar2 columns?
If that's the case then you have a problem, since a US7ASCII character set can only handle, well, ascii data.
If you are trying to store the data in columns of nchar datatypes, then there might be a problem with literals because literals are converted to database character set first, before conversion to national (nchar) character set. Such data loss can also happen depending on how binds or oci calls are performed.
You could use the dump() function to verify what's actually stored in a database column, without a db - client conversion happening that may distort the facts.
Example:
SQL> select col, dump(col, 1016) from table where some_condition;

I don't know anything about kawa but I would be
surprised if you couldn't set the file encoding it -
taken that it is quite popular. If you can't do it
you'll have to change your editor. At least Jext knows
unicode: www.jext.orgyup i m quite surprised too. Kawa cannot support chinese character so i used another editor to input all the chinese characters i need and use kawa to compile..
and it works.
tks a lot..

Problems in displaying chinese characters with utf-8 encoding

Hi,
I got problem in displaying chinese characters in my web application.
I am creating a web application supporting both English and Chinese charaters. What I am trying to do is:
1. storing some chinese characters via a web page (page1) into database.
2. retrieve the chinese characters via another web page (page2) from the database.
Once I put the Chinese characters on the webpage (page1 in step #1), it displayes well (the readable chinese characters) before I submit this page (after submit, the data will be stored into the database).
But when I tried to display the chiese characters via page2 in step#2, I got un-readable characters displayed.
The running configuration is: Sun Application Server (coming and with the JSC2) and MySQL server 5.0. And I setup the database server with utf8 as character-set.
It seems like the chinese characters got messed up throught the round-trip (from page1<----via jdbc---->database<----via jdbc------>page2).
From the database, I found the chinese characters are there. Any helps are appreciated.

Hi,
I am trying to insert new record.The record may contain chineese or English data.
I did same what u specified.
first I converted to the byte UTF8.again,I converted byte to string using 8859_1.
the values are not storing chinese characters.
pls suggest me.
below is my code.

Traditional and Simplified Chinese characters couldn't be displayed!

Hi all,
Recently I installed an Oracle 9i Database Server (9.0.1).
Problem regarding the globalization support issue was encountered after the installation of Oracle 9i Database Server. Parameters in NLS table had been checked that the language is initially set to AMERICAN, territory is set to AMERICA and the character set is UTF8.
Since traditional and simplified chinese characters must be required for the HK server, it is believed that the above parameters should be altered to TRADITIONAL CHINESE / SIMPLIFIED CHINESE, HONG KONG and ZHT16MSWIN950 / ZHS16CGB231280 respectively.
I tried to alter the NLS_DATABASE_PARAMETERS, but its not working; should the NLS_SESSION_PARAMETERS be changed instead? I also tried this one, changes is taken place but the chinese characters still couldn't be displayed, just bunches of 亂碼 (meaningless codes) instead.
Another piece of information is that the Oracle server is installed on the basis of Windows Server 2003 Standard Edition, should the Language for non-Unicode programs (which is in the Advanced page of the Regional and Language Settings) be configured to Chinese (HKSAR)? Various combinations, in terms of English (US), Chinese (HKSAR), Chinese (PRC), Chinese (Taiwan), had been taken turns to test for the results. However, same results happened.
Hence, how should we configure? Please advice us.
P.S.# It is known that this question should be placed in the "Globalization Support" forum, I have done that; however, it is hoped that I could seek more advice in here.
Thx in advance.
Karen

Karen,
Setting up such an environment requires some sophistication and know how. I would advise reading though the Globalization Support Guide and som of the papers on the Globalization Home Page http://www.oracle.com/technology/tech/globalization/index.html
before randomly attempting to change parameters. If your requirement is to store and retrieve both TRADITIONAL and SIMPLIFIED CHINESE then your database needs to be Unicode (UTF-8). Designing an application that allows you to easily access multilingual data requires careful design and planning. If you are simply trying to quickly display data you have in your database you might want to use iSQL*PLUS which is browser based and will allow you to display Unicode data. It might also be helpful to take a look at the following paper: http://www.oracle.com/technology/tech/globalization/pdf/globalization-best-practices.PDF

Chinese Data Fields not displaying Chinese Characters

Hi There,
Wonder if someone can help. We are currently running reports in Crystal 8.5 but are in the process of upgrading our business systems to latest version and this includes converting all our Crystal 8.5 reports to Crystal Reports XI R2 SP4.
During the process we are experiencing some difficulties in displaying Chinese characters, which have previously worked fine in version 8.5. The system we are running Crystal from has Oracle client 11 installed and the OS system locale is set to Chinese PRC. Our application is displaying Chinese characters properly and if we have any text fields on the report, these are also displaying properly when changing Font to Arial Unicode MS. The only thing that doesn't display properly is the field data which after checking has the correct Chinese data stored in the database. For some reason Crystal 11.5 doesn't seem to be transferring the data correctly which points to some sort of encoding problem.
Is there something I am missing here or is there something else I need to install for this to work?
Any hep would be appreciated.

What is your Oracle database's language set? Is it set to UTF-8 or non UTF-8 (such as American_America.WE8ISO8859P1" )?
There is a similar issue tracked under ID ADAPT00528561 (Crystal cannot display non-UTF-8 Chinese characters from an Oracle database ) and has been fixed and you should set the following registry key to make it effective:
Set the following registry key "UseOSLocaleForConversion" to "Yes" under:
HKEY_LOCAL_MACHINE\Software\Business Objects\Suite 11.5\Crystal Reports\Database\Oracle

²Ý ----------------------------------------> Getting a junk character instead of chinese If I was using putty, are the above steps enough to get chinese characters displayed ?
Our ssh client is Tectia (not putty).
According the below ML Note, the SSH client has to configured correctly to use globalization features.
+The correct NLS_LANG setting in Unix Environments [ID 264157.1]+
Googling "Tectia + Chinese" didn't return useful results

I understand that you are talking about Windows SSH Client.
For Putty, you should set:
$ export LANG=zh_CN.UTF-8
$ export LC_ALL=zh_CN.UTF-8
$ export NLS_LANG="SIMPLIFIED CHINESE_CHINA.AL32UTF8"
and configure Putty in Window->Translation to use UTF-8.
There is nothing about this subject on Tectia website and in their manuals, so my best guess is that the client requires Windows code page to work correctly. In such case you need to set your Windows system default locale (locale for non-Unicode programs) to Chinese and use the following settings on the server:
$ export LANG=zh_CN.GBK
$ export LC_ALL=zh_CN.GBK
$ export NLS_LANG="SIMPLIFIED CHINESE_CHINA.ZHS16GBK"
Verify with 'locale -a' that the setting zh_CN.GBK is supported on your system.

How to display Chinese characters in Oracle?

I am using Oracle 8i with Language settings as AMERICA.
I am displaying records which is contain Chinese characters.
But it is not displayed properly in Oralce.
How to change the settings to display Chinese characters?
Thanks

It could be possible to display Chinese characters using SQL Developer without any specific NLS_LANG setting because SQL Developer is using JDBC which doesn't use NLS_LANG setting according to When is NLS_LANG used ?.
For example, I'm able to display the following Chinese character in SQL Developer 1.2.0 on Windows XP Pro with French Windows setting and NLS_LANG set in Windows registry to FRENCH_FRANCE.WE8ISO8859P1.
select unistr('\8349') from dual;

Problem displaying chinese characters

I have got the problem with displaying chinese characters in the webpage after fetching the data from database.
I am using Oracle IAS webserver and oracle 8i as the database which is in UTF-8 characterset.I am getting the out put in the chinese if I use this code.
String value1 = new String(value.getBytes("ISO8859_1"), "GB2312");
I am getting the out put using this code in this format

2. Does device type/Spool Server support the font
           Goto Transaction SPAD and click Output Devices
3. SAP level Multibyte setting in place
           Click ALT + F12
           Select Options -> I18N
           Tick Activate Multibyte functionality
4. Is appropriate font for the language used
          For Simplified Chinese (ZH) language use font CNHEI, CNKAI, CNSONG

Displaying Chinese Characters in a JLabel

I wish to display Chinese characters in a JLabel WITHOUT setting the JLabel's font. The following code works fine under Java 1.4.x for Mac OSX, and Java 1.5 for Windows. However, the characters do NOT display properly under Java 1.4.x for Windows. Does anyone have any idea why? I really need to get this to work under 1.4.x for Windows without having to call JLabel.setFont(...). Maybe it's a known bug in 1.4.x that has a workaround (hopefully)?
        javax.swing.JFrame frame = new javax.swing.JFrame("Chinese Test");
        JLabel label = new javax.swing.JLabel("\u54C8\u7F57", javax.swing.JLabel.CENTER);
        frame.getContentPane().add(label, java.awt.BorderLayout.CENTER);
        frame.getContentPane().setSize(200, 200);
        frame.setLocation(50, 50);
        frame.setSize(200, 200);
        frame.setVisible(true);

1. I do not wish to set the Font on the label(s) because we have localized our application in many languages using a custom localization scheme and I do not want to change all of the code.
2. Yes, I have all the forms of Chinese installed on my Windows system.
3. I found that if I use an HTML string of the form: <html><body><font face="SimSun">\unicode chinese chars...
then THAT WORKS. The JLabel renders the String in Chinese. This might be a good option for us.
4. All of it works automatically without the need for an HTML String under Java 1.5 because evidently 1.5 has built-in support for setting the proper font on the widget after analyzing the unicode characters.

The "blue bar" no longer properly displays Chinese characters.

I recently updated my Adobe Reader from 7 to 9.4, and since doing so, Firefox no longer displays Chinese characters in the title bar. Instead, I now only see question marks.
I've added Chinese to the preferred languages and also tried switching the browser's text to Unicode, but neither of these has made a difference.
It's certainly a minor issue, but if anyone knows what to do, I'd greatly appreciate the help!
Thanks!

A possible cause is that Firefox has a problem with the (system) font that is used to display the Chinese characters on the title bar.
Were any new fonts installed recently?
You can try to use the system file checker to see if there are any problems with font files.

Display Chinese Characters

What needs to be done to make PRS-950 display Chinese characters in MS Word format? Please help!

The Reader can display text written in English fonts and other Latin-based languages such as Spanish, French and German, however it cannot display Chinese characters on text based files. The Reader does support PDF documents in other languages however, so Chinese PDF files should display fine.
