How to prevent Terminal's character encoding from changing

I have a command-line script that runs continuously, and occasionally echos to STDOUT some binary data that, apparently, changes the way Terminal displays certain characters. Is there any way of preventing this from happening? Say, by locking down Terminal's character-encoding?
...Rene

Rene,
I am not sure if you can prevent this thing from happening but you can set things back to normal by using the reset.
Another possible solution is to write the output of STDOUT to a file so that it will not be displayed on screen.

Dear all,
How to prevent a text in script from displaying if its value is zero

but it's not working.

Hello Nagaraju,
                       What you were doing is partially right.
The correct format to write in the script is as follows :
/: if &PRICE& ne 0.
&PRICE&
/: endif.
This should work. Let me know how it goes.

Character Encoding is changing random

Hello,
For a short while I'm having the next problem:
When I am using FireFox, after a while characters on pages are showed as 'boxes'. With setting backView -> Character Encoding to ISO-8859-1 the characters are shown correctly again.
I do not understand why the character encoding is changing random to UTF-8, while I have selected the ISO-8859-1 and set automatically recognize to false.
In the options menu I have also set default 'ISO-8859-1' as default character encoding.
Hoping someone can tell me why it random changes and why the same page can be show correctly for 10 times, but the 11th time the character set has changed? And of course how can I solve this problem.

I do know a website can determine the character encoding, but the strange part of the problem I occur is that the same page can be shown 10 times correctly, but an 11th time the characters like é and ë, are shown as 'blocks'/'questionmarks'.
Is there an explanation for that behaviour?

How can I tell what character encoding is sent from the browser?

Hi,
I am developing a servlet which supposed to be used to send and receive message
in multiple character set. However, I read from the previous postings that each
Weblogic Server can only support one input character encoding. Is that true?
And do you have any suggestions on how I can do what I want. For example, I
have a HTML form for people to post any comments (they may post in any characterset,
like ShiftJIS, Big5, Gb, etc). I need to know what character encoding they are
using before I can read that correctly in the servlet and save in the database.

From what I understand (I haven't used it yet) 6.1 supports the 2.3
servlet spec. That should have a method to set the encoding.
Otherwise, I don't think you can support multiple encodings in one
instance of WebLogic.
From what I know browsers don't give any indication at all about what
encoding they're using. I've read some chatter about the HTTP spec
being changed so it's always UTF-8, but that's a Some Day(TM) kind of
thing, so you're stuck with all the stuff out there now which doesn't do
everything in UTF-8.
Sorry for the bad news, but if it makes you feel any better I've felt
your pain. Oh, and trying to process multipart/form-data (file upload)
forms is even worse and from what I've seen the API that people talk
about on these newsgroups assumes everything is ISO-8859-1.

Detecting character encoding from BLOB stream... (PLSQL)

I'am looking for a procedure/function which can return me the character encoding of a "text/xml/csv/slk" file stored in BLOB..
For example...
I have 4 files in different encodings (UTF8, Utf8BOM, ISO8859_2, Windows1252)...
With java I'can simply detect the character encoding with JuniversalCharDet (http://code.google.com/p/juniversalchardet/)...
thank you

Solved...
On my local PC I have installed Java 1.5.0_00 (because on DB is 1.5.0_10)...
With Jdeveloper I have recompiled source code from:
http://juniversalchardet.googlecode.com/svn/trunk/src/org/mozilla/universalchardet
http://code.google.com/p/juniversalchardet/
After that I have made a JAR file and uploaded it with loadjava to my database...
C:\>loadjava -grant r_inis_prod -force -schema insurance2 -verbose -thin -user username/password@ip:port:sid chardet.jarAfter that I have done a java procedure and PLSQL wrapper example below:
   public static String verifyEncoding(BLOB p_blob) {
       if (p_blob == null) return "-1";
       try
        InputStream is = new BufferedInputStream(p_blob.getBinaryStream());
        UniversalDetector detector = new UniversalDetector(null);
        byte[] buf = new byte[p_blob.getChunkSize()];
        int nread;
        while ((nread = is.read(buf)) > 0 && !detector.isDone()) {
            detector.handleData(buf, 0, nread);
        detector.dataEnd();
        is.close();
       return detector.getDetectedCharset();
       catch(Exception ex) {
           return "-2";
   }as you can see I used -2 for exception and -1 if input blob is null.
then i have made a PLSQL procedure:
function f_preveri_encoding(p_blob in blob) return varchar2 is
language Java name 'Zip.Zip.verifyEncoding(oracle.sql.BLOB) return java.lang.String';After that I have uploaded 2 different txt files in my blob field.. (first one is encoded with UTF-8, second one with WINDOWS-1252)..
example how to call:
declare
   l_blob blob;
   l_encoding varchar2(100);
begin
select vsebina into l_blob from dok_vsebina_dokumenta_blob where id = 401587359 ;
l_encoding := zip_util.f_preveri_encoding(l_blob);
if l_encoding = 'UTF-8' then
   dbms_output.put_line('file is encoded with UTF-8');
elsif l_encoding = 'WINDOWS-1252' then
   dbms_output.put_line('file is encoded with WINDOWS-1252');
else
    dbms_output.put_line('other enc...');
end if;
end;Now I can get encoding from blob and convert it to database encoding and store datas in CLOB field..
Here you have a chardet.jar file if you need this functionality..

Wrong character encoding from flash to mysql

Hi, im experiencing problems with character encoding not
functioning correctly when sending from flash to mysql. What i am
doing is doing a contact form in flash which then sends the value
to a php file which takes the values and inserts them into a table.
As i'm using icelandic charecters i need the char encoding to be
either latin1 or utf8 in mysql, or at least i think so. But it
seems that flash or the php document isn't sending in the same
format as i have selected in mysql because all special icelandic
characters come scrambled in the mysql table. Firefox tells me
tough that the html document containing the flash movie is using
utf-8.

I don't know anything about Icelandic characters, but Flash
generally really likes UTF-8. So it should be sending that if that
is what it is starting with.
You aren't using any kind of useCodePage? That will mess it
up.
Are you sure that the input method is Icelandic?
In the testing environment can you list variables (from the
debug menu) and see if they look proper? If they do then Flash is
readying them correctly and the problem must be coming in further
down stream.

How to prevent IPV6 entries in DNS from server End

Hello,
My concern is to stop the IPV6 DNS entries being added to the DNS , but the main goal is to prevent it from the server end instead of going and disabling the IPV6 entries on each client machine.
I have gone through this article but my goal is to fix it from the server end
http://social.technet.microsoft.com/Forums/en-US/cd1a87f0-caf3-498e-9a20-e728e474b626/how-to-prevent-ipv6-addresses-from-being-registered-in-dns-server?forum=winserverDS
Looking forward for the reply.
Muhammad Asif Server Administrator Linux/Windows

Hi,
You can use Group Policy to disable IPV6 on clients within your domain, assuming you have an Acgive Directory environment.
There are ADM/ADMX templates that are actually doing this. You just have to import it on PolicyDefinition folder on one of your domain controller then configure a group opliy and link it to your structure.

Hope this help.

How can I prevent the active Tab Group from changing whenever I close a tab?

Simply, often I will close a tab in Firefox 4; then, for some reason the active Tab Group changes to some other collection. It usually happens when I close the last tab in my tabs bar, but it has happened after closing other tabs, as well. Would love to prevent Tab Groups from changing automatically. Thank you!

Hi:
I tried precisely your suggestion before posting my message to the forum yesterday. I just forgot to mention it... Maybe I was afraid of increasing my message length more and more...
I already know that this solution prevents the MediaTracker from blocking. However...
(1) If they reach a troublesome image (like a Targa), the users of my application might not be pleased by its freezing for 10 seconds. Actually, this image loading module is part of an architecture for database applications from which my development team and I produce applications for various customers. Images are used, in particular, in Oracle BLOB support.
(2) If I use a smaller timeout delay, I have no guarantee that any image, whatever its length, will load properly (Targa excluded, of course). According to tests I performed yesterday, I am virtually sure that the 10-second delay will be busted very easily by pictures larger than 1 Mb. I cannot overlook this potential problem: an Oracle BLOB can contain up to 2 terabytes of data!
On the other side, I don't want to focus too much the attention on the JIMI Targa import filter because I know that a revised version of the JIMI and JAI packages will be part of JDK 1.4. This is why I am trying to figure out what is happening in the MediaTracker and Toolkit classes, which are much more fundamental than the Jimi ones...
Thanks anyway...
Best regards,

How do I lock columns or rows from change

I want to keep a couple of columns from changing.
This is to prevent inadvertent changes in passwords or user Id.
How do i do that.

Waterdoc,
Numbers allows you to lock a whole table but individual cells. This means that it is best to design, upfront, your data so that user input data is in one table and calculations are in other tables (which you can lock). There is no facility for login access by user. There is the ability to lock a document using the document inspector:
See the last section. This is single password for the whole document.
You can post suggestions to Apple directly using the menu item "Numbers > Provide Numbers Feedback"
Best regards,
Wayne

How can I prevent the settings on iMessage from changing each time I sync the devices with iTunes on our iMac?

Each time I sync an apple device (iPad, iPad mini, iPhone) with iTunes on our iMac the settings on iMessage and phone settings change. We use the same Apple ID and have different e-mail addresses and phone numbers; however, each time a device is sync'd on iTunes on our iMac, the iMessage settings and phone settings are changed so that we all each get each other's text messages and phone calls. After the device is sync'd/charged, I have to go into each device (all of them somehow update when only one is sync'ing) and re-set the settings to what we want. How can I prevent settings from being changed each time?

Okay I've tried safe mode. Let it run down to 98%, plugged it in, locked the screen, and waited. A few minutes later, the screen came on showing the 100% icon at the top right, full battery icon just to the left of the time, 100% text to the left of that.
I'm not going to do a hard reset until I have confirmation that this is not normal behavior for the phone because that's going to take hours of my time and gigabytes of data transfer to get all of my media and apps back on the phone and configured.
After all my griping, I do have to give credit where it's due. This phone is much more efficient than my Galaxy Nexus. I left the S5 running in WiFi hotspot mode while on battery last night. It still had over 50% left on the battery. The Galaxy Nexus would be stone dead after about 4 hours. I can live with that if I have to but I'd really rather be able to leave it on the charger at night.
