Western european an Polish character set

Dear gurus,
I 'm work on oracle database 10R2 server with Western European character set. We now want to include polish character to suit a new customer. Inorder to keep our wester eurpean languages (English, danish, swedish etc) and the new polish, I converted the database server and the window webserver client to Unicode UTF8 but I am unable to retrieve some polish characters such as ( ą ć ę ł ń ś ż ź) as they are display differently from the original characters.
If the know the best character set/how to configure the database to support both western european (not only english) and polish character sets please share your view.
regards

Before you can determine whether the characters are displayed correctly, you need to determine that they are stored correctly.
The dump function is useful for this
For example if I dump this entire string
select dump('ą ć ę ł ń ś ż ź') from dual;
I get the following
Typ=96 Len=23: 196,133,32,196,135,32,196,153,32,197,130,32,197,132,32,197,155,32,197,188,32,197,186
and dumping individual characters, eg
select dump('ą') from <yourtable>l;
Typ=96 Len=2: 196,133
I do this test with OracleSqlDeveloper running on the Database Server which has a UTF8 characterset
Check out the globalisation guide. The basic principle here is that the NLS_LANG character setting on your client should be the same as on your server.
eg if you are using a windows client and your server NLS_LANG is set to AMERICAN_AMERICA.UTF8 and teh NLS_LANG setting in the windows registry is AMERICAN_AMERICA.ASCII7, then you would need to change the NLS_LANG setting in the windows registry to AMERICAN_AMERICA.UTF8.
This would then resolve the issues with client display.
So,the steps here are (and in order)
1) Ensure your Data is stored correctly on the server (Insert on server )
2) Ensure your Data is retrieved correctly on the server(Retrieve on server)
3) Ensure your data is displayed correctly on the Client(Retrieve on Client)
That should hopefully resolve your problem. The Globalisation guide as mentione dearlier is your place of reference

Western iso 8859-1 character set is gone, "other (including Western" does not work. Why did you take it out?

Some websites need Western ISO 8859-1 character set to run properly and you have taken it away in favour of "other(including Western)", now the site does not work properly. Why did you take it out and can you please put it back.

ISO-8859-1 and Windows-1252 should be equivalent. Can you provide an example of a page that doesn't display properly?
If you have to manually select a character encoding to view the page correctly, then the site is broken and you should notify its owner that it needs be fixed. Websites specify the character encoding in one of two ways:
* [http://www.w3.org/International/tutorials/tutorial-char-enc/ Handling character encodings in HTML and CSS | W3C]
# The ''Content-Type'' response header.
# The ''meta'' tag in the page source.

Polish character sets

Hi reader,
do you have a clue how to set character set or how to to switch between character sets? e.g. from cp1252 to 1250 and vice versa
I'd like to display polish characters within a swing GUI and do not know how to switch....
internationalization works fine (based upon Messages_iso.properties) but the character set does not switch to something fitting.
thx

Java-internal character set is UTF-16, there should be no need for "switching". Property files, however, are restricted to ISO-8859-1 and may use Unicode escape sequences (\uxxxx). Maybe you should check the contents of your property file.

Approach to converting database character set from Western European to Unicode

Hi All,
EBS:12.2.4 upgraded
O/S: Red Hat Linux
I am looking for the below information. If anyone could help provide would be great!
INFORMATION NEEDED: Approach to converting database character set from Western European to Unicode for source systems with large data exceptions
DETAIL: We are looking to convert Oracle EBS database character set from Western European to Unicode to support Kanji characters. Our scan results show
both “lossy (110K approx.)” and “truncation (26K approx.)” exceptions in the database which needs to be fixed before the database is converted to Unicode.
Oracle Support has suggested to fix all open and closed transactions in the source Production instance using forms and scripts.
We’re looking for information/creative approaches who have performed similar exercises without having to manipulate data in the source instance.
Any help in this regard would be greatly appreciated!
Thanks for yourn time!
Regards,

There are two aspects here:
1. Why do you have such large number of lossy characters? Is this data coming from some very old eBS release, i.e. from before the times of the Java applet interface to Oracle Forms? Have you analyzed the nature of this lossy data?
2. There is no easy way around truncation issues as you cannot modify eBS metadata (make columns wider). You must shorten or remove the data manually through the documented eBS interfaces. eBS does not support direct manipulation of data in the database due to complex consistency rules enforced by the application itself (e.g. forms).
Thanks,

Character set mapping (western european to US ascii)

Hi everyone,
I am trying to convert a string with western european character set to US Ascii character set. Idea is to remove all "accent" on top of the "accented characters"
Here is an example .À should be converted to A.
I have tried using the following, but some characters are not converted.
SELECT decompose(to_single_byte('ÀÁÂÃÄÅÆÇÈÉÊËÌÍÎÏÐÑÒÓÔÕÖ×ØÙÚÛÜÝÞßïîíìëêéèçæåäãâáà'))
FROM dual;
The result is :
AAA?A??CEEEEIIII??OOO?O??UUUUY??iiiieeeec??a?aaa
As you can see, 12 characters converted to questions marks, meaning they didnt converted properly like others.
I will appreciate any suggesstions or code example of how people have tried to convert western european character set to US Ascii.
Thanks

According to doc
Where a character does not exist in the destination character set, a replacement character appears. .
I can understand that × Ø Æ Þ ß are not ASCII characters but it's strange that some characters with ~ and ° "accents" are not considered as ASCII. Maybe you can try to code your own function in PL/SQL to handle these special cases and then call this function in SQL.

Oracle 10G support for both Cyrillic and Western European Character Sets

Dear all,
Our DB currently supports western EU characters sets but we need to also support Russian Characters.
Is there a common character set for both? or some trick that does the job?
Thanks.
DB: Oracle 10G R2
OS: Linux
Current Char Set:
NLS_CHARACTERSET     WE8ISO8859P1
NLS_CALENDAR     GREGORIAN
NLS_NCHAR_CHARACTERSET     AL16UTF16

AL32UTF8 will always do the job.
CL8ISO8859P5
CL8MSWIN1251
could to the job according to http://download.oracle.com/docs/cd/B19306_01/server.102/b14225/applocaledata.htm#sthref1960.

Lanovo ix4 300d and european character set for samba shares

Hi,
I am installing a couple of IX4-300d at a client site, struggling to set and fix the samba character set for the Windows shares. Here in Italy everyone is used to put western european characters into filenames (for example è ò ° €) but the NAS acts wierdly when it finds such caracters in folder names and file names.
As you know samba gives the possibility to declare dos charset= ISO8859-1 and unix charset= ISO8859-1 in the smb.conf file but the option is not present in the IX4 setup pages.
Is there an easy way to circumvent the problem and fix this option? As it is now the machine is fearly useless, at least if you need to migrate files and folder from a server or storage with ISO8859 charset already applied.
thanks a lot

This issue has been raised on all iomega drives since day 1. although 'documented' it is still shame, that units sold to 'r-o-w' means rest-of-world, outside US, are stuckto Aa-Zz09 basically wheras client systems ( windows, linux, ios ) don't care and take what they are supposed to do.

Website not displaying correctly. Firefox is changing the character set to Western (ISO-8859-1) automatically.

Normally I have set Firefox (or it's set by default) to Character Set Unicode (UTF-8) and everything displays perfectly. I've never had a problem before.
Now however, whenever I upload my own website, for some bizarre reason on that particular tab (and only that tab) the Character Set is changed over to Western (ISO-8859-1) and then there's a few characters within my site that do not display correctly, namely apostrophes and hypens.
It definitely isn't my software (Serif WebPlus X4) because the page displays correctly in every other browser. Plus it displays correctly in Firefox if I change the Character set back to Unicode.
PS The site is a work in progress

That happens because the server sends a content-type (<b>text/html; charset=ISO-8859-1</b>) via the HTTP response headers and in that case that content type prevails. The page code is saved with an UTF-8 byte order mark (ï»¿) that you see in this case.

Need to add Polish option to character set menu in SAP Gui

Basis Gurus,
We have installed the Polish language on our unicode R/3 system and now
need to add it as a character set option in the Gui menu.
Menu Path:
Customize Local Layout --> Character Set --> (Missing Option for Polish)
I have searched OSS and online resources and have not found out how to
add an entry in this menu.
I did alter the file frontEN.txt in which the menu entries are built,
but did this not add the entry.
Can you please advise on the procedure to add this entry. Our
developers need it to view special Polish characters in their SapScript.
Thanks,
Jeff Martens

Deepak,
Thanks for the reply. I've read that document before, it's helpful with some of the I18N settings, but does not explain how to add a language to the "character set" menu.
Does anyone know if this is possible?
Thanks,
Jeff

File sender adapter and content conversion with polish character

We are loading a csv file with PI 7.0 file sender adapter using "content conversion" - all fields go through EXCEPT a special character hex '208C' (space in front) looks like "Æ" is converted to hex 'C28C'.
We are using code page UTF8
We are using:
enclosuresign "
enclosuresignescape ""
fieldcontentformatting nothing
enclosureconversion NO
Hope some one can help

Hi Bohamo,
Hope you have set the following for your file sender adapter :
1. Transfer Mode is set to Binary,
2. File Type Text,
3. Encoding ISO-8859-1( for Western European Latin ).
Inorder to recognize Polish Character, try as follows :
Your sender file after coming into Pi has XML encoding declaration 'UTF-8'.
Write a simple XSLT mapping to change the value of the attribute "encoding" to "ISO-8859-1" in the output XML of message mapping . Include this XSLT map as the second mapping step in your interface mapping.
First step in your interface mapping will be your already existing message mapping.
An example of the XSL code :
<?xml version='1.0'?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method='xml' encoding='ISO-8859-1' />
<xsl:template match="/">
<xsl:copy-of select="*" />
</xsl:template>
</xsl:stylesheet>
or you can also do java mapping if you are comfortable with java code !
Cheers,
Ram.

Oracle XE and character set

Hello all,
I installed Oracle XE on RHEL 4 Linux and I found out that database character set is AL32UTF8. Does anyone know why oracle choose this character set? Maybe because of NLS_LANG env variable? Is it possible to change it to EE8ISO8859P2? Since database is still empty I can drop it and crate new database.
Do you think it is possible to set some env variables and do new oracle xe instalation including database with iso charset?
I want to have EE8ISO8859P2 charset because of doing exp/imp from another oracle iso db to oracle xe and it is much easier to do this without charset conversion.
Any help will be appreciated.
regards,
Miha

When you download XE, you have a choice - take the 'western european' character set download, or the 'unicode' download.
No other choices.
Join us over in the XE forum where people have discussed this and found workarounds. Info about finding that forum at Re: Oracle XE Installation failed

Changing CHARACTER SET in OracleXE

Because this is my first post in this forum I like to say first "Hello" !
I do my first steps after installing OracleXE (OracleXEUnv.exe). In the database informations I saw that the Character Set (NLS_CHARACTERSET) is "AL32UTF8"., but I want to change it to "WE8MSWIN1252".
When I tried the SQL command "ALTER DATABASE CHARACTER SET WE8MSWIN1252;" but the system shows the message "ORA-12712: Der neue Zeichensatz muss eine Obermenge des alten Zeichensatzes sein".
How can I change the NLS_CHARACTERSET parameter ? Could it be that I have to deinstall this version und use instand the western european version (OracleXE.exe) ?
Kind regards, Michael

Could it be that I have to deinstall this version und
use instand the western european versionYup. You already knew the answer :)

Changing DB character set for only one schema

We are interested in changing the characterset of only one user from Western European to AL32UTF8.
Could you please verify if the following steps will be correct to do the same.
1. Run CSScan on the one user
2. Fix any issues
3. Export that one user (with NLS_LANG set to <your old database character set>)
4. Create a new database in the AL32UTF8 character set
5. Import that one user into the new database (with NLS_LANG set to <your old database character set>)

Actually your title is a little incorrect. You are not changing CS for only one schema in existing DB which is not possible. You are trying to migrate a schema to new CS DB. Which is totally doable and your approach is mostly correct.
Database Character Set Scanner provide user scan mode
http://download.oracle.com/docs/cd/B19306_01/server.102/b14225/ch12scanner.htm#i1006013
Mostly the issue could be data truncation, especially if you have column defined using char or varchar2 vs nchar and nvarchar2
because char/varchar is defined in bytes, AL32UTF8 is multi-bytes char set, some character of your old data could saved more than 1 bytes in new DB and can't fit into the column size.

Character set error oracle 10g

I have a 10g TARGET database with a single byte character set of western european and 9i SOURCE databse with multibyte character of UTF8 since the character sets are different to load data from 9i to 10g I am using national character set NCHAR columns on target database to store the multi byte data :
this is the table i am working on loading
CREATE TABLE RAN_TEST1_MDL
( MODEL_ID NUMBER(15) NOT NULL,
PRODUCT_ID NUMBER(15) NULL,
MODEL_CODE NVARCHAR2(540) NULL,
ODM_CODE NVARCHAR2(900) NULL,

The table is test table on oracle 10g database .
This is the query I am running
INSERT /*+append*/ INTO WORK_HIER_MDL(

SELECT
MODEL_ID,

shld_hier_mdl is source table from oracle 9i multi byte UTF8 database.
WORK_HIER_MDL is target table on oracle 10g single byte western european databse
Error : ORA-29275: partial multibyte character
When I describe the source table SHLD_HIER_MDL ( on 9i oracle accesed thru a db link ) I get the following error
ORA-01460: unimplemented or unreasonable conversion requested
I think ORA-29275 and ORA-01460 are correleted . Can anyone suggest what could be the cause for this ? Thanks

Error:     ORA-29275 (ORA-29275)
Text:     partial multibyte character
Cause:     The requested read operation could not complete because a partial
     multibyte character was found at the end of the input.
Action:     Ensure that the complete multibyte character is sent from the
     remote server and retry the operation. Or read the partial
     multibyte character as RAW.
you can export the table and import on 10g.Rename the table,create your test table and use IAS.

Oracle 10g db character set issue

I have a database 10g with database character set western
european "WE8ISO8859P1" and we are receiving data from source
database with database character set as "UTF8" during data load
for one of the tables we receive the following error "ORA-29275:
partial multibyte character" I understand this might be due to
the fact western european character set is not a subset/superset
of UTF8 .Am i right ? What would be the way around this ?

It is certainly possible that the issue is that your database characterset is a subset of UTF8.
How are you getting the data? Are we talking about a flat file? A query over a database link? Something else?
Does the data you're getting contain characters that cannot be represented in the ISO-8859 1 character set? It is quite common to send UTF-8 encoded files even when the underlying data is representable in other 8-bit character sets (like ISO-8859 1).
What are you trying to do with the data? Are you trying to load it into a CHAR/ VARCHAR2 column? A CLOB? A BLOB? An NCHAR/ NVARCHAR2? Something else?
