Remove unicode control character

hey, so i've asked this around a few places and recieved no answers, but the arch community seems like a bunch of smart people and i've recently switched over from ubuntu.
is there a way to remove input methods and unicode control characters from the context (right-click) menu? i've searched and searched, but i've had no luck with this.
there's a way to remove it in gnome with gconf, but i've tried that, and no luck.
i'm using openbox, and i think i found something about my gtkrc file along these lines
gtk-show-input-method-menu =
gtk-show-unicode-menu =
both are "gboolean" which i don't know what it is, or if this is even what i want.
any help would be appreciated, as i never use these menus.

U+2415, SYMBOL FOR NEGATIVE ACKNOWLEDGE is not a control character. It is a normal symbol character, which is a substitute display character used when the control character U+0015 NEGATIVE ACKNOWLEDGE is to be displayed instead of being interpreted.
You need to refine your question.
In general, you can remove any particular character or characters from a string using the SQL functions TRANSLATE or REPLACE. You can use CHR or UNISTR to encode characters that you cannot enter from a keyboard. You can use REGEXP_REPLACE with POSIX character classes to remove broader ranges of characters.

'Zero-width Non-Joiner' Unicode Control Character for Xperia International Keyboard in Persian

I use Xperia International Keyboard in Persian (Farsi) on my Xperia Z3 Comapct. I really like its Gesture input for Persian. On the other hand I like Google Keyboard for Persian for its 'Zero-width Non-Joiner' Unicode Control Character key.This character is used in Persian as a non-breaking space or "نیم‌فاصله". But Google keyboard lacks gesture input for Persian. I would like it like very much If there is a ZWNJ (U+200C) key on next updates of Xperia International Keyboard for Persian. It would be perfect if it also have Arabic Decimal Separator (٫) (U+066B) and Arabic Thousand Separator (٬) (U+066C).

Removing unicode control characters from string

Hi.
I have a webservice where I return an object (with some strings) back to the client. The information is read from a database, and the string can sometimes contain invalid xml characters (like unicode 0x13). This results in an error when parsing the information at the client side.
Is there someway a easy way to set up a filter or something that checks whether the string contains characters outside the valid range specified for XML's (lower than unicode 0x20 etc), and removes them/replace them with a different character?

If you have to get rid of the control chars then       String someText = "a\nb\nc\td\re\r\nf";
        String someTextWithoutControlChars = someText.replaceAll( "[\u0000-\u0020]","");
        System.out.println(someTextWithoutControlChars);but like kaj says, some control chars are valid.

How to remove Unicode from XML file

I get following error when unmarshal xml:
[java] org.xml.sax.SAXParseException: An invalid XML character (Unicode: 0x15) was found in the element content of the document.
Anyone know how to remove Unicode from xml file? Can I remove the unicode by rebuild the file?
Thanks

These sort of error usually occur when you're using a different character encoding to read the file than the one you wrote it with. Perhaps if you were to post the problem section of the file and/or the code that created it in the first place.

Suppress Page eject control character...

Hello,
While generating a report in text mode, Report Builder adds a page eject control character(i.e. ctrl-l) at the end of report.
We don't want this control character. So how can this be removed ?
We are using Reports 6i.
Thanks
Kiran.

When running a character mode report it uses a .prt file to determine the printer escape characters. There is a dflt.prt which contains the page break character value. If you remove this then you will remove the page breaks from your character output.

10.4.9 removes Brightness Control from System Preferences?!

Has anyone else noticed that the Intel 10.4.9 update has removed Brightness Control from their System Prefs?!
maybe it's just mine... seems unlikely!!!

No, mine still has it. Perhaps it no longer thinks you can adjust the brightness. You may try the "standard" repair techniques to see if it will come back: Repair permissions, repair the disk (you must start up from installer DVD or use Safe Mode--which takes a while to boot because it is checking the disk), and then running the combo updater instead of Software Update.

Removing unwanted control characters in exported text files

I am currently evaluating Crystal Reports 2008 to determine applicability to our requirements. I need to export data files to continuous text to be read by other application software. I have successfully created the files but have what I believe to be page feed or end-of-page control characters (small rectangles) in the output. Can someone enlighten me as to how I can suppress or remove these control characters?

In the export to text options enter 0 for the number of lines per page. This will produce an unpaginated text document without the page control markers.

Remove last newline character

How can I remove the newline character only from the very end
of a string? (Note there are several newline characters within the
string). Thanks!

How long is the string and roughly how many newline
characters are there? One way, although kinda funky, would be to
convert the newline-delimited list to an array, and then convert it
back. See below.

Invalid control character 0 at position 7, Error Code : UFGUIEZK

When I first login obiee dashboard, it would error about "invalid control character 0 at position 7".
But if I click a select button, it would show the result what I want it.

Hi Joe,
(Especially using the IE8 brower)
When I enter any dashboard pages, (not the login page...) it would error about "invalid control character 0 at position 7".
I press the "Backspace" button. (I keep a same brower and same session.)
Then I enter same dashboard. It doesn't mention about the error message. -_-; It works....
What's the points is...
OBIEE is working~
I can use any answers... can make any dashboards.
Everything is gonna all right...
Except... If I wanna the any dashboard, I would enter the page twice.
Thanks for your concern~!

How to remove new line character from query output?

Hi,
How to remove new line character from query output?
have tried select replace(column_name, CHR(10), ' ') from table_name.
Edited by: GreenHorn on Sep 11, 2008 12:53 AM

Please consider, that windows uses a sequence of chr13||chr(10) Unix uses only one character chr(10).
The new line character(s) may be OS-dependent.
You could consider both with:
replace(replace(column_name, CHR(13)||CHR(10), ' '),CHR(10),' ')

Help! - Distorted Add Remove List control!

Can anyone tell me why on some pc's my Add Remove list control appears stretched out - that is, the right-side 'selected' list box will extend to the left covering the add/remove buttons and the same 'selected' box is only half drawn from the left side (right side missing), including the title being truncated, and the title is then duplicated to the right in its entirety. (It is hard to describe but I can provide a screenshot if needed).
As soon as an item is selected or de-selected, it re-adjusts itself to normalcy!
It seems to be a browser independent problem which ONLY happens on SOME pc's and NEVER on others! This leads me to suspect an out-of-date jar or class file on the local pc but I can't seem to find anything inconsistent.
CAN ANYONE HELP?! It is preventing us from putting this page into production and I would hate to have to write my own replacement, as it would take more time than we have.
Thanks in advance for your assistance,

Remove logitech control center

Hi All
New to the world of MAC. Can someone tell me step by step exactly how to remove the control center? I just installed a vx nano mouse and I think control center is causing the macbook to crash.
Thanks in advance.
Jason

Hi there,
simply go to Logitech's website, download the "LCC" installer package. Inside the dmg-file you'll find a little program called "Uninstaller" - that's what you're looking for.
Enjoy!
