Fallout from removing "illegal" characters?

It seems Time Machine requires that your computer name does not contain special characters, including spaces and apostrophes. This was an eye opener for me, because if I recall, it was Setup Assistant itself that generated and prompted me to accept the default computer name, based on my user name. I clicked OK, and so "<user>'S Computer" has been floating on my screensaver for years.
But after all, I want to follow the rules in this regard. The point of backups is to icrease reliability so if Time Machine can't hang with spaces apostrophes, I'll get rid of mine.
But, I am wondering what the consequences will be? There must be other folks here who've already changed their computer name for this. Are there any drawbacks? In the past, changing disk names has caused me problems with licenses and so forth. Can I expect the same type of problems if changing my computer name? Any other considerations?

We can use the CHR() function to represent ASCII characters. This is particularly useful with the non-printing characters such as the linefeed...
SQL> select 'hello'||chr(10)||'world' from dual
2 /
'HELLO'||CH
hello
world
1 row selected.
SQL>Cheers, APC

Sql to remove special characters from my search

Hi everyone. I'm very new to sql and have hit another road block. I am doing a query on my database in oracle sql developer. I want to search manufacturer numbers but sometimes they were entered with dashes ( 999-99-9999) and other times not (999999999) is it possible to apply a function to overlook the dash in both my query numbers and in the database mfr_nbr column?
any help would be appreciated.

ok, I have built a nesting string of replaces to remove all of my special characters and it worked perfectly but now I am not sure where to place the nest later in the string to remove it from my search of mfr numbers. The reason I need to do it again is because I want to remove the characters so I am searching in terms of " apples to apples" so to speak. here is my string so far. I still need to add the part where I put in my search for the manuf_item_nbr. my question is where do I need to place the nested replace's to remove it from my numbers I'm going to search?

Removing illegal chars from Filename

I want to rename some files, but the destination filename may have some illegal characters in it.
I looked around a bit but I couldn't find anything that could help.
I was expecting a char array of illegal chars which I could use to remove them.
So is there any standard way to remove those characters?
If not, what is a good way to get rid of them?

DvdKhl wrote:
Well I know about hte replacing methods,
but I would still need to know which characters to replace.
Of course I know the illeagal chars defined by Windows,
but I guess different OSes have different restrictions. (Or are they the same in Windows & Linux?)
...AFAIK, they are not the same. And there are of course more OS'es than those two, with, no doubt, other restrictions. And sicne Java is not geared towards one OS (like NET), Java does not have such a built-in method for removing characters.

Remove control characters in txt file (saved from Excel)

Hi,
I have a txt file that contains invisible control characters and I want to remove those characters. I've been thinking of 2 options
1/ Get the content of the file into a string, then go through each character and basically takes only alphanumeric, new lines, Alt+Enter character (character that is created in txt files in Excel that breaks line). With this approach, I'm stuck on getting the character code for Alt+Enter so if anyone could point out. That helps a great deal.
2/ Use some pattern matching {ctrnl} or something to remove all control characters. I've tried this approach and it didn't work for me.
Please help me with this problem. Any help or suggestion is greatly appreciated.

(saved from Excel) Why not save it as csv?

You can figure that out with a hex editor or just write a small app that prints int values for each byte, not character, and print the file.
Presumably you already found the Character class and its methods.

Removing unwanted characters from imported string

Hello,
I have a tab-delimited .txt file which I have to import into Indesign for further processing.
The file is composed by a 3 columns header row at the beginning (Code, Description, price) followed by a series of 3 columns data rows.
The problem is that sometimes, depending on the way the txt/csv file has been created, may include unwanted characters (such as spaces, double spaces, etc.).
Is there a way to "clean" the imported strings from these unwanted characters?
This is my starting code:
function processImportedTxt(){
 //Open .csv file
 var csvFile = File.openDialog("Open file .csv","tab-delimited(*.csv):*.csv;");
 datafile = new File(csvFile);
 if (datafile.exists){
 datafile.open('r');
 var csvData = new Array();
 while(!datafile.eof){//read every row till the end of file
 csvData.push(datafile.readln());
 datafile.close();
 for(a=1; a<csvData.length; a++){
 var myRowData = csvData[a];//row of data
 var mySplitData = myRowData.toString().split("\t");//divide columns
 var myRowCode = mySplitData[0];
 var myRowDesc = mySplitData[1];
 var myRowPrice = mySplitData[2];
 // Here goes code for cleaning strings from unwanted characters
processImportedTxt();
Any help would be much appreciated
Thanks in advance

Hi,
If you want to safe 1-space occurences just a small correction:
i.e.:
var myRowCode = mySplitData[0].replace(/\s\s+/g,'');

Illegal characters removal .

Hi all,
We are getting some illegal characters, when we checked the product details it has "-" character but on the site it is showing "?" character. Even when tried with valueishtml="true" did'nt helped. We cant touch any Java classes for right now, is there any solution in jsp side , or any droplet is there which i am not aware of ? can anyone suggest us how to resolve this please .
Just for the record our application is UTF-8.
Thanks,

I think Gautam may be on the right track. It sounds like your character is stored correctly in the database and is getting replaced by ? either in the jdbc driver or in the GSA repository code when ATG fetches the db record. The fact that you're seeing ? in both /dyn/admin and the ACC leads me to that conclusion. /dyn/admin is a mix of jhtml and plain html. The ACC is a java Swing app. The repository layer must think the character is a ?. If the repository layer has the wrong character, you'll never be able to fix it in your jsp code.
There are some properties of GSARepository that affect character set translation. The properties are useSetAsciiStream, useSetBinaryStream, and useSetUnicodeStream. They're described in the SQL Repository Reference chapter of the ATG Repository Guide. Every repository has its own copy of the properties. I don't know of any cases where the ootb property values do the wrong thing for the Oracle db, but it's something you could play with if you're still stumped. First make sure you're running with the ootb values for the repository that's causing trouble. Then try changing the values (one at a time) to see if they make any difference. You might have to restart your ATG server for each change to take effect.

Filelist illegal characters

using LabVIEW 7.1 I want to list and read several files in a certain directory.
I want to recursively search and read these files starting from a root-directory,
however the directory-path at some point contains illegal characters, probably because the data is originating from Japan.
Now the recursive filelisting is not able to look beyond that part of the directory.
Windows displays these chars as 3 square's, and Labview displays them as 3 question marks, and generates a error.
I could ofcourse manually rename the illegal chars, but since intent to analyse lots of these files, doing a manual rename would be too much work.
Does anyone know a solution for this problem ??
Thanks in advance ,
René

leaving the rest intact. Couldn't find anything yet ...
René
You could experiment with the command line in Windows. Not sure if the command line will support such file names at all but if it goes bad there, then you are indeed in deep trouble. Try to start a command line and do a dir command in such a directory. Then try to do a rename on such a file. It might work.
I doubt there is a GUI application that does specifically do this task, so you may have to resort to a batch file script doing it on the command line if the above experiment shows you that this is possible at all.

Cannot insert Captivate Demo - filename contains illegal characters

RoboHelp HTML v8 on XPpro. Captivate v4.
I have created a simple Captivate v4 application demo and published to SWF.
In my RHhtmlv8 project, I create a new topic, and choose Insert > Adobe Captivate Demo.
The Insert dialog allows me to select my SWF file. It shows it in the Insert dialog and starts to play it.
No matter what my SWF filename is (e.g. abc.swf, video1.swf, etc.), when I click the OK button in the Insert dialog, I get the error:
'Unable to rename file, "abc.swf". The filename contains illegal characters.'
I have searched the forums here and find no solution.
How do you get support from this company? I went to the support link and it only showed Captivate as an option, even though I have a valid license for RH8 and have registered it. Yet - for 2 days now, I have not heard back from any support via that mechanism.
Jeff

Hi Jeff
When you attempt to insert the demo, by chance do you still have the project open in the Captivate editor? If so, you likely need to close it there before attempting to insert into RoboHelp. I've seen all manner of weirdness with this.
Another thing that seems to have happened recently that is worth looking at. When you Published your Captivate demo, did you Publish as AS2 or AS3? (For those that may wonder, AS refers to ActionScript. Similar to JavaScript and is the Flash programming language.)
I've begun to notice issues with inserting Captivate content where I have published as AS3.
Let us know... Rick

Need to remove special characters

Hello All
Some input is comming from source field, if any special characters comming from source field, I need remove special characters and send data source to target field. please suggest me how will i do .
Thanks&Regards,
Venkat

Hi Venkat,
check this thread.
Handling Special Characters
check the document :
https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/502991a2-45d9-2910-d99f-8aba5d79fb42
Depends upon encoding methods handling will differ,
you can use ISO-8859-1 or ISO-8859-2 instead of UTF-8 for some special characters.

Insert 'illegal' characters into file name for print label?

Hey all (Happy New Year)
I actually see some people here who helped me with this originally so many years ago (hi 'x'). Any way, I'm using this .js file to annotate aerial imagery prior to printing, and I know just enough about scripting to make changes to the basic layout as needs arise - until now. A new rather anal retentive mgr doesn't like substitutions I've made for a few 'illegal' characters that windows doesn't allow in file names. For example, the file name used for the annotation is:
001 0003 1in = 660ft CFL 154_074 01-01014 503-013.tif
But Mr. mgr doesn't like the in, the ft and the use of the _ instead of a period (.) so what I need is a modification that goes something like (and note I DO NOT CODE, so stop laughing) -
"look for in and replace with ", look for ft and replace with ' and look for _ and replace with , " so the final annotation written to the image is:
001 0003 1" = 660' CFL 154.074 01-01014 503-013.tif
My current .js is below, I'd really appreciate any assistance. Thanks! TLL
// CREATE NEW CANVAS W/SPACE ON TOP
var deltaW = 0; // add 'N' pixels to the width
var deltaH = 150; // add 'N' pixels to the height
var anchor = AnchorPosition.BOTTOMCENTER; // anchor point for canvas resize
// SET FONT TYPE AND SIZE - use GetFontName.js to get exact name
var fontName = "ArialMT";
var fontSize = 18;
 // Check if a document is open
 if ( documents.length > 0 ) {
 var originalRulerUnits = preferences.rulerUnits;
 preferences.rulerUnits = Units.PIXELS;
 try {
 var docRef = activeDocument;
 docRef.resizeCanvas(docRef.width + deltaW, docRef.height + deltaH, anchor);
 // Create a text layer at the front
 var myLayerRef = docRef.artLayers.add();
 myLayerRef.kind = LayerKind.TEXT;
 myLayerRef.name = "Filename";
 var myTextRef = myLayerRef.textItem;
 // ADD FILE EXTENSION, change the n to y below
 var ShowExtension = "n";
 myTextRef.size = fontSize;
 myTextRef.font = fontName;
// SET TEXT COLOR in RGB values
var newColor = new SolidColor();
 newColor.rgb.red = 0;
 newColor.rgb.green = 0;
 newColor.rgb.blue = 0;
 myTextRef.color = newColor;
// SET POSITION OF TEXT - PIXELS from left first, then from top.
myTextRef.position = new Array( 30,110);
 // Set the Blend Mode of the Text Layer. The name must be in CAPITALS
 // ie change NORMAL to DIFFERENCE.
 myLayerRef.blendMode = BlendMode.NORMAL;
 // select opacity in percentage
 myLayerRef.opacity = 100;
 // The following code strips the extension and writes tha text layer.
 // fname = file name only
 //use extension if set
 if ( ShowExtension == "y" ) {
 fname = docRef.name;
 } else {
 di=(docRef.name).indexOf(".");
 fname = (docRef.name).substr(0, di);
 myTextRef.contents = fname;
 // docRef.flatten("n");
 } catch( e ) {
 // An error occurred. Restore ruler units, then propagate the error back
 // to the user
 preferences.rulerUnits = originalRulerUnits;
 throw e;
 // Everything went Ok. Restore ruler units
 preferences.rulerUnits = originalRulerUnits;
} else {
 alert( "You must have a document open to add the filename!" );

I did some quick testing and here is what I have seen.
I went into a cygwin shell and successfully did this:
$ touch t\"est\'t.jpg
$ ls t\"*
t"est't.jpg
This means that the underlying file system (NTFS) is able to correctly encode both the ' and " characters, at least as far as cygwin is concerned.
However, from the Windows command line and Explorer point of view, the ' is OK but the " is not. The characters /\"*?<>:| can't be used in file names in Win. This means you can get the ' and . characters working but not the " character.
From the js side, the code would look like:
var x = "001 0003 1in = 660ft CFL 154_074 01-01014 503-013.tif";
var str = x.replace(/in/, '"').replace(/ft/, "'").replace(/_/, '.');
alert(str);
Which displays
001 0003 1" = 660' CFL 154.074 01-01014 503-013.tif
The string stuff is easy, but while you can save a file with ' and . you can't use " via js. You can't even do it using the PS UI manually.
I've tested and verified this. Let Mr. Mgr know that it is not possible to completely comply with his requests. Unless, of course, you upgrade to OS X : )

ADF Faces Components Demo - Illegal Characters error

Hi ,
I downloaded the ADF Faces Components Demo for version 11.1.2.3.0 from http://www.oracle.com/technetwork/developer-tools/adf/downloads/index.html . I tried following instructions :ADF Faces Components Demo Install Instructions
This is getting downloaded as rcf-dvt-demo.zip. I renamed it to rcf-dvt-demo.war.
Then I tried to create a project from this war... and got following error :
The project file "C:\rcf-dvt-demo.war!\Project.jpr" is not valid. The file name may contain illegal characters, it may be too long, or permissions for this file or one of it's parent directories may be restricted.
Please help . Am i downloading from correct location and following the correct instructions.
Thanks,

Good Catch Timo ... Lot of thanks.
Still I will put down the silly mistake of overlooking the wizard.
I was doing the correct thing - "create a new application and inside this application workspace you add a new 'project from war'." But mistake was .. First step of wizard it is project name and path,, and then second step is war location... and in hurry I was giving the project name and war location in first step.
Thanks,

Removing unwanted characters..

Hey guys,
I'm back for help again. Unfortunately my brain isn't creative enough, so please help! :-)
Ok, I need to remove unwanted characters from a file...the problem is that the characters look like this:
in any text editor. I'm using JEdit, and it's ISO-8859-1 encoding. The text was initally from a html file, and i think that most of the html is displayed well as text in JEdit. But these squares, which are bits of info that I don't need, are making it a little trick to do my extraction.
Ex: the word I want to extract is "trouble". But in the file, it looks like this:
troble....
Anyone know how to get rid of all that stuff???
Thanks in advance.
...DJVege...

you could try to set a filter on the characters you accept. Process each character and only accept those that fall into some ASCII boundary. If you accept ASCII characters that have values between 33-255, most blocks should be eliminated.
Something like this should help:
import java.io.*;
public class Example {
 protected static final int MIN_ASCII = 33;
 protected static final int MAX_ASCII = 255;
 public Example(String file) throws IOException {
 BufferedReader b = new BufferedReader(new InputStreamReader(new FileInputStream(file)));
 PrintStream p = new PrintStream(new FileOutputStream(file+"_fix.txt"));
 String s = "";
 int j;
 while ((s = b.readLine()) != null) {
 for (j = 0;j < s.length();j++) {
 if (valid(s.charAt(j))) {
 p.print(s.charAt(j));
 p.println();
 b.close();
 p.close();
 protected boolean valid(char c) {
 int asc = (int)c;
 // allow for tabs and spaces
 if (asc == 9 || asc == 32) {
 return true;
 return (asc >= MIN_ASCII && asc <= MAX_ASCII);
 public static void main(String args[]) {
 if (args.length > 0) {
 try {
 new Example(args[0]);
 catch (IOException e) {
 e.printStackTrace();
}useage: java Example <file>
of course, something like this will probably only work on "english" files as I dont have an understanding on how foreign characters are encoded..
if this doesnt solve your problem, you might want to adjust the range to 33-127, which will eliminate all "block" characters and all "special formatted" characters (i.e. accented characters, currency signs, etc.)
see http://asciitable.com/ for more information on ASCII characters

Sql: remove special characters

Hello!
maybe someone has a hint for me how to remove special characters such as tab/new line characters from columns?
Thanks in advance!
Tiberius

Hmm... actually it's straight forward:
drop table mytexts
create table mytexts (comment varchar(50))
insert into mytexts values ('This is a standard text!')
insert into mytexts values ('There comes a TAB <--')
insert into mytexts values ('This is called a newline
<--<')
select * from mytexts
| COMMENT |
| -------------------------------------------------- |
| This is a standard text! |
| There comes a TAB <-- |
| This is called a newline
<--< |
3 rows selected (1375 usec)
sqlcli db770=> select replace (replace(comment, ' '), '

| -------------------------------------------------- |
| Thisisastandardtext! |

Removing special characters

Hi,
I have to remove special characters from string and replace it with space.
Kindly help its urgent.
Thanks

Hi,
You Can use Overlay command for this.
Syntax
OVERLAY text1 WITH text2 [ONLY pattern].
Effect
Characters in the text1 variable are replaced by characters in the text2 data object which are there in the same location. If the ONLY addition is not specified, all blank characters in text1 are replaced. If the ONLY addition is specified, all characters are replaced that occur in the pattern data object, and upper and lowercase is taken into consideration. If the lengths of text1 and text2 are different, text1 is processed using the shorter length only.
CONSTANTS initial_time TYPE t VALUE IS INITIAL.
DATA: time TYPE t,
text(4) TYPE c.
text = '12'.
time = text.
