Change default character set of JVM

Is there a way to change the default character set of JVM to say, UTF-8?
System.out.println("Default Character Set: " + new java.io.OutputStreamWriter(new java.io.ByteArrayOutputStream()).getEncoding());
System.out.println("File Encoding: " + System.getProperty("file.encoding")); On Windows
==========
Default Character Set: Cp1252
File Encoding: Cp1252
On Linux
========
Default Character Set: ASCII
File Encoding: ANSI_X3.4-1968
I would like to save on the effort of changing the many lines of code that looks like
new BufferedWriter(new OutputStreamWriter(out)); to
new BufferedWriter(new OutputStreamWriter(out, "UTF-8")); Thanks

Try this:
-Dfile.encoding=utf-8
as vm argument.

UTF8 as system default character set

Hi,
I'm new to OSX and I moved to a new company few days ago. We work with Tiger workstations and servers, several Linux internet servers and Windows Laptops.
One of the problems I have is to find a way to set UTF8 as the default character set for the system, not just user level preferences. That would solve many of my other problems.
There is probably an easy way to do that?!!
Any tip or trick would be greatly appreciated.
Thanks.

What are your problems exactly? If you give some specifics, someone can probably help.
Generally speaking Unicode UTF-8 is what OS X uses by default for a lot of things. The exception would be the file system, which uses UTF-16 NFD. There is certainly no way to change that.

System wide default character set

Hi,
I moved to a new company few days ago where we use Tiger workstations and servers.
I've been trying to figure a way to set UTF8 as the default character set for a whole system, not just a user preference.
I suppose there is a way to do that, but I'm afraid I won't have more time to find it.
Any help is welcome.

If you could explain exactly why you think you need to do that, someone might be able to help.

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.

Changing the character set in RoboHelp 7 file converted from 5

The character set of the output files for WinHelp defaults to
utf-8. How can the default be set to windows-1252 per project or
for all projects in RoboHelp 7?

This is related to the posting - "RoboHelp 7 (with patch) IE6
does not display popup field definitions". Somewhere in our
environment the character set is getting changed to western
european (ISO) for the pages that do not load initially in IE6/XP
from the OAS even though the code generated by RoboHelp is utf-8.
The WebHelp generated in RoboHelp v5 has a characterset of
windows-1252. None of the pages with the character set of
windows-1252 have a problem loading (or changing the character
set). The problem may be on the OAS or the single signon
layer.

[SOLVED] default character set in mousepad

Is there a way to set the default character set in mousepad? I want it to always save in utf-8, but it defaults to iso-8859-1.
It's a big pain when you're trying to save something that you've copied from a browser. I always have to go back and type the filename again (and change to utf-8) after getting the error message about not being able to save.
Also, is there a way to set the default locale to utf-8 instead of iso-8859?

You put me on the right track; the problem was that I left the .utf8 part out of the LC_ALL= line in /etc/profile
EDIT: Oops, accidentally put a - between utf and 8. That won't work!

Change original character set

Hello,
I have installed the Oracle BI Standard Edition One version and I would like to change the original multi-byte character set that is defined by default to another character set single-byte (WIN1253 or ISO8859-7), is this possible? If it is possible, how can I change the character set?
Thanks.

Changing database character set from US7ASCII to AL32UTF8

Our database is running on Oracle database 10.1.0.4.0 (AIX) The following are its parameters:
SQL> select value from NLS_DATABASE_PARAMETERS where parameter='NLS_CHARACTERSET';
VALUE
US7ASCII
We would like to change the database character set to AL32UTF8. After following Metalink notes: 260192.1 (which helped us resolve "Lossy" and "Truncated" data, the final output of the CSSCAN utility is:
[Scan Summary]
All character type data in the data dictionary are convertible to the new character set
All character type application data are convertible to the new character set
[Data Dictionary Conversion Summary]
The data dictionary can be safely migrated using the CSALTER script
We have no (0) Truncation and Lossy entries on the .txt file. We only have Changeless and Convertible. Now accdg to the documentation, we can do a FULL EXP and FULL IMP. But it did not detail how to do the conversion on the same database. The discussion on the document tells how to do it from one database to another database. But how about on the same database?
We cannot use CSALTER as stated on the document.
(Step 6
Step 12
12.c) When using Csalter/Alter database to go to AL32UTF8 and there was NO "Truncation" data, only "Convertible" and "Changeless" in the csscan done in point 4:)
After performing a FULL export of the database, how can we change its character set? What do we need to do the the existing database to change its character set to AL32UTF8 before we import back our dump file into the same database?
Please help.

There you are! Thanks! Seems like I am right in my understanding about the Oracle Official Documentation. Thanks!
Hmmmmm...when you say:
*"you can do selective export of only convertible tables, truncate the tables, use CSALTER, and re-import."*
This means that:
1. After running csscan on database PROD, i will take note of the convertible tables in the .txt output file.
2. Perform selective EXPORT on PROD (EXP the convertible tables)
3. Truncate the convertible tables on PROD database
4. Use CSALTER on PROD database
5. Re-import the tables into PROD database
6. Housekeeping.
Will you tell me if these steps are the correct one? Based on our scenario: This is what i have understood referring to the Official Doc.
Am i correct?
I really appreciate your help Sergiusz.

How to change the character set of the D/b

Hello All,
When i issue the command
ALTER DATABASE CHARACTER SET UTF8
It gives me the error that I can only change the character set to a superset of the existing character set.
Is there any way i can change the character set without recreating the database.
TIA
Naveen

The existing character set is the basis for the new character set. This is fair enough, because the character set determines how the actual data is stored in the database. Allowing new characters is a minor change: completely re-encoding your entire database is not.
I'm afraid export, recreate and import is your only option.

How to change the character set encoding not being a superset one

HI, i have a fresh installed database, but i realize the character set support in my client is not good enough, since its a not production database i want to change the character set encoding to anothor one not being a superset of the old one.
I have tried the "ALTER DATABASE CHARACTER SET WE8MSWIN1252" but it fails claiming i need a superset one.
I guess its just a single steps to do it, i have all the privileges, just not the time to reinstall and setup everything.

Do you know what that does to the existing data, though? My hunch would be that any characters which have a different binary representation in the source & target character sets would be corrupted.

How to change the Character Set from AL32UTF8 to WE8DEC

Hello!!
I want to know how to change the character set in the database from AL32UTF8 to WE8DEC.
I tried to use the comand ALTER DATABASE CHARACTER SET but I got an error because WE8DEC is not a superset of AL32UTF8.
I need to import tables from a server that uses WE8DEC. So when I do the import to my server, wich has AL32UTF8 , I can't import the rows that include an Ñ.
So I want to change the caracter set to WE8DEC. How can I do it?
Is it needed to change the language configuration? The remote server has AMERICAN_AMERICA, and my server has MEXICAN SPANISH_MEXICO (both uses text in spanish).
Thanks a lot!!

When you export from WE8DEC server what did you use
for NLS_LANG char set? And when importing?
The export was done in another computer because I can't do the export in the server (I have 10g, and the remote server has 9i and the export is not working). In my server, when I tried to do the import, the NS_LANG value was MEXICAN SPANISH_MEXICO.WE8MSWIN1252.
When I try to import to my database I got the error:
import done in WE8DEC character set and AL16UTF16 NCHAR character set
import server uses AL32UTF8 character set (possible charset conversion)
export client uses WE8MSWIN1252 character set (possible charset conversion)

Change Database Character Set to Arabic!

Dear All,
My database is Oracle 11gR2 On Linux platform.
I am trying to change the character set of my database to store Arabic characters.
This is what I am doing:
SHUTDOWN IMMEDIATE;
STARTUP MOUNT;
ALTER SYSTEM ENABLE RESTRICTED SESSION;
ALTER SYSTEM SET JOB_QUEUE_PROCESSES=0;
ALTER SYSTEM SET AQ_TM_PROCESSES=0;
ALTER DATABASE OPEN;
ALTER DATABASE CHARACTER SET INTERNAL_USE AR8ISO8859P6;
SHUTDOWN IMMEDIATE;
STARTUP;
When i check:
SQL> select value from NLS_DATABASE_PARAMETERS where parameter='NLS_CHARACTERSET';
VALUE
AR8ISO8859P6
But still when i query data it shows it like this:
"¿¿¿¿¿¿ç ¿¿ê ¿¿¿¿çê¿ ¿¿¿¿ ¿¿¿ ¿¿¿¿¿¿ ¿¿¿¿ ¿¿¿èê¿ ¿¿¿è¿ ¿¿¿¿ê¿¿ ¿¿¿ ¿¿â¿¿ ¿¿é ¿¿¿ è¿¿¿ ¿ê ¿¿¿¿ êè¿ ¿¿¿¿¿¿ 28/9 ¿ê ¿ ¿¿é ¿¿¿¿ ¿è¿¿ê èç¿¿¿ ¿è¿¿¿ âê¿¿ ¿¿¿ è¿¿â¿ ¿¿è¿"
Can you help me to understand where is the problem and how to get through it.
Regards, Imran

Why on earth are you using the undocumented INTERNAL_USE command? The name alone should strongly imply that this isn't something that normal users should be playing with. It is extremely likely that you've corrupted your database.
Do you have a backup of your database taken before you corrupted it? If so, can you restore that backup? Once you do that, tell us what character set you're starting with. If you are implying that there is existing data in the database, what character set is that data encoded with? Can you DUMP the data to verify this?

Default Character Set using JSObject

Hi All,
This problem has been nagging me for a while and am now resorting to this forum for an answer.
I have a jsp page with an embedded applet. Inside the applet, I read the HTML page using JSObject.
The problem is when using the JSObject to get values of controls from the HTML page with Japanese characters.
The HTML page is encoded in UTF-8, however, when I get values from the controls using JSObject in the applet, the values returns as ???. Latin characters are supported but not Japanese characters. So.. I'm wondering what character set the JSObject supports when converting a Javascript string to a Java String.
The following code is executed:
          JSObject win = JSObject.getWindow(this);
          JSObject doc = (JSObject) win.getMember("document");
          JSObject forms = (JSObject) doc.getMember("forms");
     JSObject form = (JSObject)forms.getSlot(0);
          JSObject title = (JSObject)form.getMember("title");
String titleValue = (String)title.getMember("value");
I've also tried form.eval("document.forms[0].title.value") and that returns the same ??? for japanese characters.
Any ideas?
Kent

Hi Larry,
The characters that appear at the beginning of each file - ï»¿ - is the BOM or byte order mark for UTF-8, which is automatically added to the file on creation. These files are UTF-8 encoded, to allow for the support of multi-byte characters. An updated version of the Exporter Tool removes these BOM characters. Please contact Support to obtain this updated version of the Exporter tool.
Alternatively, you can try the following:
If the character set of your Oracle database is not UTF-8, then you have two options:
1) If possible, change the character set of your database to UTF-8. To check the current database characterset, check the "NLS_DATABASE_PARAMETERS" table.
or
2) Open the generated .dat files using Notepad, then use the File | Save As menu option, and set the "Encoding" to ANSI, then save the file. The BOM will now be removed from the .dat files.
I hope this helps.
Regards,
Hilary
