Make sure that you have a Unicode font that supports Chinese characters. I have been testing the support of Unicode text (allows many other character and image based languages to be displayed) and have found that it depends on what fonts are available on the system you're viewing the report on. Unicode is supported in Crystal (since version 9 I believe) but it will display '?' or '[]' if there isn't a font to render the text properly.
This font supports loads of languages: http://www.code2000.net/code2000_page.htm

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;

How to retrieve distinct rows from oracle table without using 'DISTINCT' keyword in SQL?
Thanks in advance.

Welcome to the forum.
Besides GROUP BY you can use UNIQUE instead of DISTINCT as well, but that's probably not wanted here ;) , and the ROW_NUMBER() analytic:
SQL> create table t as
2 select 1 col1 from dual union all
3 select 1 from dual union all
4 select 2 from dual union all
5 select 3 from dual union all
6 select 4 from dual union all
7 select 4 from dual;
Table created
SQL> select col1 from t;
      COL1
         1
         1
         2
         3
         4
         4
6 rows selected
SQL> select distinct col1 from t;
      COL1

How to get utf-8 Chinese Characters from Oracle DB by EJB

We have found that after disabling JIT in weblogic, the Chinese can be displayed correctly, otherwise, it doesn't work.How come this happens?

Thanks for all of your suggestions. It still refuses to work.
I entered the following: ��^�E on the HTML form using the Chinese(PRC)keyboard on my Win2K box.
I checked and verified the correct encoding in the servlet request (GB2312 for chinese characters)
request.getParameter(xxx) yields ???
new String(request.getParameter(xxx).getBytes("GB2312")) yields three boxes (values 20309, 27946 and 23380)
new String(request.getParameter(xxx).getBytes("GB2312"), "UTF-8") yields nothing
Any ideas?

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;

The preferences don't necessarily matter. You most likely need to adjust the encoding in View > Text Encoding. If you will provide the url of an example page where you have a problem I can probably offer more specific help.

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.

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:

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.

How to get up and running with WebUtil 1.06 included with Oracle Developer Suite 10.1.2.0.2 on a win32 platform
Solution
Assuming a fresh "Complete" install of Oracle Developer Suite 10.1.2.0.2,
here are steps to get a small test form running, using WebUtil 1.06.
Note: [OraHome] is used as an alias for your real oDS ORACLE_HOME.
Feel free to copy this note to a text editor, and do a global find/replace on
[OraHome] with your actual value (no trailing slash). Then it is easy to
copy/paste actual commands to be executed from the note copy.
1) Download http://prdownloads.sourceforge.net/jacob-project/jacob_18.zip
and extract to a temporary staging area. Do not attempt to use 1.7 or 1.9.
2) Copy or move jacob.jar and jacob.dll
[JacobStage] is the folder where you extracted Jacob, and will end in ...\jacob_18
     cd [JacobStage]
     copy jacob.jar [OraHome]\forms\java\.
     copy jacob.dll [OraHome]\forms\webutil\.
The Jacob staging area is no longer needed, and may be deleted.
3) Sign frmwebutil.jar and jacob.jar
Open a DOS command prompt.
Add [OraHome]\jdk\bin to the PATH:
     set PATH=[OraHome]\jdk\bin;%PATH%
Sign the files, and check the output for success:
     [OraHome]\forms\webutil\sign_webutil [OraHome]\forms\java\frmwebutil.jar
     [OraHome]\forms\webutil\sign_webutil [OraHome]\forms\java\jacob.jar
4) If you already have a schema in your RDBMS which contains the WebUtil stored code,
you may skip this step. Otherwise,
Create a schema to hold the WebUtil stored code, and privileges needed to
connect and create a stored package. Schema name "WEBUTIL" is recommended
for no reason other than consistency over the user base.
Open [OraHome]\forms\create_webutil_db.sql in a text editor, and delete or comment
out the EXIT statement, to be able to see whether the objects were created witout
errors.
Start SQL*Plus as SYSTEM, and issue:
     CREATE USER webutil IDENTIFIED BY [password]
     DEFAULT TABLESPACE users
     TEMPORARY TABLESPACE temp;
     GRANT CONNECT, CREATE PROCEDURE, CREATE PUBLIC SYNONYM TO webutil;
     CONNECT webutil/[password]@[connectstring]
     @[OraHome]\forms\create_webutil_db.sql
     -- Inspect SQL*Plus output for errors, and then
     CREATE PUBLIC SYNONYM webutil_db FOR webutil.webutil_db;
Reconnect as SYSTEM, and issue:
     grant execute on webutil_db to public;
5) Modify [OraHome]\forms\server\default.env, and append [OraHome]\jdk\jre\lib\rt.jar
to the CLASSPATH entry.
6) Start the OC4J instance
7) Start Forms Builder and connect to a schema in the RDBMS used in step (4).
Open webutil.pll, do a "Compile ALL" (shift-Control-K), and generate to PLX (Control-T).
It is important to generate the PLX, to avoid the FRM-40039 discussed in
Note 303682.1
If the PLX is not generated, the Webutil.pll library would have to be attached with
full path information to all forms wishing to use WebUtil. This is NOT recommended.
8) Create a new FMB.
Open webutil.olb, and Subclass (not Copy) the Webutil object to the form.
There is no need to Subclass the WebutilConfig object.
Attach the Webutil.pll Library, and remove the path.
Add an ON-LOGON trigger with the code
         NULL;

JEditorPane -- displaying chinese characters in browser

Is it possible to display chinese characters in an applet in a browser, I have read Jaric S.'s article on it.. but it is a little confusing.. however without doing any of that coding I have chinese showing up on one machine in IE, but not on any other machines with IE. Any thoughts anyone?

IE. Any thoughts anyone?Browser Java is particularly sensitive to the version of Java the browser supports. Some browser companies, notably Microsoft, haven't updated their Java implementation in 4 years. Likewise users who are using old versions of other browsers probably have old versions of Java. This makes it very hard to predict how anything will work when it depends on a browser's VM.
There are two ways to combat this. First you can use Sun's Java Plugin to replace the VM used by your browser with a modern one that supports your applet. Second, you can use Java WebStart which allows programs to be launched from a browser but run in an independant VM. These two things might help you get consistent results for your applets.
Hope this helps,
Brian.
