Help with RTF and special characters

Hi,
I'm curently working on apex 4.1 and i want to generate an .rtf file which i fill with the information coming from a form.
I am doing so without any problems when it comes to normal Americam letters.
I face a problem when i wan't to dynamicly change my subsctitution phrases in the .rtf template with czech characters (á,é...), because i can't just replace the word with these characters in the rtf because it expects to receive some escape formats and not the letter itself.
Can anybody help me figure this one out?
I've tried creating a library of the symbols and their asci code and replacing them in the file but they don't always work. I even saved a .doc file in .rtf and copied the code from that one in my .rtf and it doesn\t work. In the original file i have some characters in my file i have other characters eventhough the code is the same...
I'm puzzled by this one and i don't know what to do.
Thank you,
Alex.

Hi,
Yes i wan't to remove information from the clob.
I have an .xml template and if i don't have any updates on some chapters i wan't to remove them.
Until now i have tried to replace the strings that i don't need using the replace function, but sometimes the string that i wan't to replace is longer than 32726 chars.
I have comented the xml clob with tags like "" and "" and using the instring and substring functions i get the piece of information i wan't to remove.
"select substr(r.template_content,instr(r.template_content,'') , instr(r.template_content,'')-instr(r.template_content,''))
from rtf_templates r
where r.template_id=3"
and then i use " clob := replace(clob,get_substr)"
usualy it works but sometimes the length of the subtr is larger than 32767 chars and that's when i have problems.
Any ideeas on how to remove the chunks of info from the clob?
Thank you.
Alex.
I have changed the get_substr select because i wrote it wrong :) now it's ok

A problem with regex and special characters

Hello,
I am using regex in my application but i have a problem with special characters. Here is the explanation of what i am doing:
I have a certain piece of text that i want to parse and replace every occurrence of a given word with some sort of a tag which have the word found inside it.
so that: go Going Go to gOschool by bus and to learn and to play GO Go
and i need to replace the word "go" (case insensitive and only at word boundaries) should be:
*<start>go<end> Going <start>Go<end> to gOschool by bus and to learn and to play <start>GO<end> <start>Go<end>*
Consider the following code and call the method with the parameter"go?"
The Matcher finds a weird match at the word "G?oing" with only the letter G !!!
It also ignores the "?" in the pattern completely.
Any clue of what is happening i would be very grateful...
private static String replaceMatches(String strToFind)
        String resultArticle="";
        String article = " "+"go? G?oing Go? to gOschool by bus and to learn and to play GO? Go?*"+" ";
        strToFind = "\\b"+ strToFind +"\\b";
        String linkPart1= "<start>";
        String linkPart2 = "<end>";
        Pattern p = null;
        try{
            p=Pattern.compile(strToFind, Pattern.CASE_INSENSITIVE);
        Matcher m = p.matcher(article);
        String[] res = p.split(article);
        int i=0;
        //System.out.println("result of split: "+res.length );
        while(m.find())
            resultArticle+=(res[i]+" ");
            resultArticle+=linkPart1;
            resultArticle+=m.group().trim();
            resultArticle+=(linkPart2+" ");
            i++;
        if(i<res.length)
            resultArticle+=res;
//System.out.println("result of match: " + i);
System.out.println(article);
//System.out.println(resultArticle.trim()+scripts);
catch(PatternSyntaxException ex){}
return resultArticle.trim();
}Thanks

because split will not work when trying to replace the first word if i don't append a space at the beginning.Split doesn't work anyway. And my question wasn't why do you add spaces (which you really don't need to do), but why do you do them with " " + "go" rather than just " go"
replaceAll will replace all the occurrences in the text with only one word. without taking into consideration the case of the word i need to replace.No.

If i use replacaAll(article, strToFind) the output will be:
<start>go?<end> G?oing <start>go?<end> to gOschool by bus and to learn and to play <start>go?<end> <start>go?<end>No. I showed you the actual output of an actual replaceAll.
which is not what i want as i need to keep the case of the words i am replacingThe replaceAll I showed you does that.
Please study the examples given and read the docs carefully rather than making claims based on inaccurate guesses.

OK....!!!!!
just download the Excel file (*.xls) and try open with Word-MS. In the document search by the string that you have mentioned in the question. (Use Ctrl +F).
If you see something like "ABC bla bla ba & instead of &amp , then you have to pass the data through the code I've mentioned.
You can get more details on encoding special characters UTF-8 in Google.com or Sun Websites etc.
You can also encode the & in hexadecimal format to get the desired output.

Remove spaces and special characters from a form field

Hi,
I am tragically new to all of this, but am trying to create a form in Adobe Acrobat 9. I am trying to use a Custom Format script to take inputs in a form field and automatically remove spaces and special characters (hyphens specifically). For example, if a user inputs "RAN-99 06" I would like it to change to "RAN9906." I found this script that will not let users input special characters
if (!event.willCommit) {
event.change = event.change.replace(/[\$#~%\*\*\^\-\+=\[\]\{\};\"\<\>\?\|\\\!]/g, "");
And that's okay, but I can't figure out how to disallow spaces. Also, the perference would be for a script to allow users to input the data as they like, but to clean it up after they leave the text field.
Thanks in advance!

From the description, I assume that the script is currently in the Keystroke event. In fact, that would be a most logical way to have it; simply ignore anything unwanted when entered.
If you want to allow the user to enter anything, but "clean it up" when done, you would place your code in the Validate event. You will have to adjust your Regular Expression so that it works globally, but that's the whole difference. This will change the value.
Note that you can also enter the code into the Format event. However, that would only change the visual representation of the value, but internally, the value would remain as entered.
Hope this can help.

Is it possible to search for strings containing spaces and special characters?

In our RoboHelp project, there are figures with text labels such as Figure 1, Figure 3-2, etc.
When I search for "Figure 3" I get all pages containing "Figure" and "3", even if I surround it in quotes. Similarly, searching for "3-2" treats the '-' character as a space and searches for all pages containing '3' or '2'.
Is there a way to search for strings containing spaces and special characters?

In that case I think the answer is no if you are using the standard search engine. However I believe that Zoom Search does allow this type of searching. Check out this link for further information.

Help with writing and retrieving data from a table field with type "LCHR"

Hi Experts,
I need help with writing and reading data from a database table field which has a type of "LCHR". I have given an example of the original code but don't know what to change it to in order to fix it and still read in the original data that's stored in the LCHR field.
Basically we have two Function modules, one that saves list data to a database table and one that reads in this data. Both Function modules have an identicle table which has an array of fields from type INT4, CHAR, and type P. The INT4 field is the first one.
Incidentally this worked in the 4.7 non-unicode system but is now dumping in the new ECC6 Unicode system.
Thanks in advance,
C

Hi Anuj,
The unicode flag is active.
When I run our report and then to try and save the list data a dump is happening at the following point
LOOP AT T_TAB into L_WA.
As I say, T_TAB consists of different fields and field types whereas L_WA is CHAR 800. The dump mentions UC_OBJECTS_NOT_CONVERTIBLE
When I try to load a saved list the dump is happening at the following point
APPEND T_DATA-RAWDATA to T_TAB.
T_DATA-RAWDATA is type LCHR and T_TAB consists of different fields and field types.
In both examples the dumps mention UC_OBJECTS_NOT_CONVERTIBLE

Help with count and sum query

Hi I am using oracle 10g. Trying to aggregate duplicate count records. I have so far:
SELECT 'ST' LEDGER,
CASE
WHEN c.Category = 'E' THEN 'Headcount Exempt'
ELSE 'Headcount Non-Exempt'
END
ACCOUNTS,
CASE WHEN a.COMPANY = 'ZEE' THEN 'OH' ELSE 'NA' END MARKET,
'MARCH_12' AS PERIOD,
COUNT (a.empl_id) head_count
FROM essbase.employee_pubinfo a
LEFT OUTER JOIN MMS_DIST_COPY b
ON a.cost_ctr = TRIM (b.bu)
INNER JOIN MMS_GL_PAY_GROUPS c
ON a.pay_group = c.group_code
WHERE a.employee_status IN ('A', 'L', 'P', 'S')
AND FISCAL_YEAR = '2012'
AND FISCAL_MONTH = 'MARCH'
GROUP BY a.company,
b.district,
a.cost_ctr,
c.category,
a.fiscal_month,
a.fiscal_year;
which gives me same rows with different head_counts. I am trying to combine the same rows as a total (one record). Do I use a subquery?

Hi,
Whenever you have a problem, please post a little sample data (CREATE TABLE and INSERT statements, relevant columns only) from all tables involved.
Also post the results you want from that data, and an explanation of how you get those results from that data, with specific examples.

I am trying to combine the same rows as a total (one record). Do I use a subquery?Maybe. It's more likely that you need a different GROUP BY clause, since the GROUP BY clause determines how many rows of output there will be. I'll be able to say more after you post the sample data, results, and explanation.
You may want both a sub-query and a different GROUP BY clause. For example:
WITH    got_group_by_columns     AS
     SELECT a.empl_id
     ,     CASE
                    WHEN c.category = 'E'
              THEN 'Headcount Exempt'
                    ELSE 'Headcount Non-Exempt'
            END          AS accounts
     ,      CASE
                    WHEN a.company = 'ZEE'
                    THEN 'OH'
                    ELSE 'NA'
            END          AS market
     FROM              essbase.employee_pubinfo a
     LEFT OUTER JOIN mms_dist_copy             b ON   a.cost_ctr     = TRIM (b.bu)
     INNER JOIN       mms_gl_pay_groups        c ON   a.pay_group      = c.group_code
     WHERE     a.employee_status     IN ('A', 'L', 'P', 'S')
     AND        fiscal_year           = '2012'
     AND        fiscal_month          = 'MARCH'
SELECT    'ST'               AS ledger
,       accounts
,       market
,       'MARCH_12'          AS period
,       COUNT (empl_id)      AS head_count
FROM       got_group_by_columns
GROUP BY accounts
,            market
;But that's just a wild guess.
You said you wanted "Help with count and sum". I see the COUNT, but what do you want with SUM? No doubt this will be clearer after you post the sample data and results.

Have a problem in Numbers with entering data directly into a cell when a table reaches a certain size and special characters are used?

I am creating a list of words with special characters in some of them. I get to a point where I cannot enter data directly into the cell. I have to use the data entry bar at the top in the toolbar. Any solutions available?
This is the table I am creating...
From row 25 on, I am only able to enter data into the cell through the toolbar at the top and not directly into the cell itself. I believe that this problem originates from the special characters I have inserted in the previous records because if I do not use special characters, then the spreadsheet acts flawlessly. Have there been issues in Numbers with data entry, the size of a table, and using special characters?

I would try removing the rows with "special" characters one at a time to see which one is causing the problem

PDFs using BI publisher and special characters - pound sterling

I have a table with character strings which include the £ pound sterling sign.
If I create an xml file from the table using the escape sequence for the pound sign & # 163; and load it into BI publisher, the pdf renders correctly using an rtf template.
If I include the pound sign in the rtf template itself the pdf renders correctly and if I use a report query in Apex based on the table, and an rtf template then the pdf renders correctly.
However there is a limit to the number of columns that can be sent to BI via the report query - we have found this to be 119 columns. For more than this we have been using a stored function to return xml data as a clob and use the clob to generate the pdf with the rtf report layout (using get_print_document). This method works fine but the pound sign is not rendered correctly (appears as "?").
The NLS_LANG is set to english_united kingdom in the database and in BI publisher. The locale in bi publisher is en_GB. BI will create the pdf correctly with the pound sign if using a standard xml file (with escape seq for pound) so I am sure it is not a language issue in BI/Apex.
Any ampersands in the xml cause the pdf to fail completely and we cannot represent special characters with a sequence containing the ampersand for this reason. I have tried "& # 163;" and "& amp;#163;" and variations and have also tried using CDATA, none of which gives the correct pdf output. I have also tried to switch the encoding to Windows-1252 or ISO-8859-1 in the header of the xml (xml generated by stored procedure so can control this), but this gives incorrect results too.
We also need to send other special characters to BI via get_print_document and apex (bullet points, ampersands, dashes ) but cannot use the escape sequences because of the ampersand problem.
Has anyone had any success with this?
Is there any plan ( for a future version of Apex) to increase the number of columns that can be used in report query using Apex/BI publisher?
Thanks
Kathryn

Hi Kathryn
I've had exactly the same problem as you've mentioned.
Firstly, I've also found that I cannot select more than 119 columns from a view using a report query and have opted to the use the stored function to return the xml (same as you).
After conducting a lot of searching and experimenting i've found that you can use the following escape characters in REPLACE in your stored function:-
'£' can be replaced with CHR(194)||CHR(163)
'%' can be replaced with '%25'
'&' can be replaced with '%26amp;'
I found the above escape characters from the xml file or by opening the xml file in Wordpad. Therefore I'm sure you'll be able to find the escape characters for the other symbols that you mentioned i.e. bullet points, dashes etc.
I hope this has helped. Good luck and let me know if you get any developments with the limitation on the number of columns that can be selected from a report query as this would save a lot of trouble (as I'm sure you're aware).
Thanks
Natalie

Accents and special characters - how to manage

Hi,
please could you explain how it is possible to handle accents and other special characters in Business Objects XI 3.1 (Universes and Reports)? Which are the parameters/settings I need to configure for
Database (ORACLE)
Application Server (AIX)
Universe
WebI
I want to display italian accents ò à è ù ì and some special characters like '@'. Even if they are correctly stored in DB, in WebI I retrieve characters without accent and a '?' for '@'
Any suggest?
Then, one more thing ...I noticed that creating a new report WebI, characters with accents appear without accents, instead if I create a report with Rich Client and I publish it, then accents are correctly displayed also opening the report with Web Intelligence. I have the application server on AIX, but Rich Client runs on WIN Server ...
Thanks a lot

Hi,
I had almost the same problem (only different language) and manged to solve it after "google-ing" these links:

FYI, system is AIX 5.3 with Oracle 10g.
I've edited .profile for boxi user and added appropriate export of NLS_LANG variable, then restarted BO and now reports are correct.
I guess you should try adding this line to .profile of your boxi user

XmlSaveDom unresolved symbol, and special characters in output...

I have a couple of issues with XmlSaveDom() that I'm hoping someone can help with...
Firstly, under windows I'm having difficulty locating the library that it lives in. I'm linking to:
oraxml10.lib (from the 10.1.0.2 XDK, the latest version I can find) and oci.lib (from the 10.2 client)...but getting an unresolved symbol on XMLSaveDom().
I'm using the XDK because under windows I only have a client install which does not appear to have any of the XML headers or libraries in it. I'm using
10.1.0.2 because it's the latest version I can find to download from technet.
Secondly, under Solaris I'm just linking to libclntsh.so from 10.1.0.2 server home, and this resolves XMLSaveDom() ok. However when I use XMLSaveDom() I find unusual special characters in the output periodically:
ÿ¾Ý <SOME_TAG>some_value</SOME_TAG>
The strange character sequence is always the same.
Any help with either of these would be greatly appreciated.

The DOM is not required to escape the characters, so it is correct that you get the literal ampersand characters when you ask the DOM for a getNodeValue().
When an XML document is serialized -- using, for example, the XMLDocument.print() method -- it is when this external form of the document is produced that escaping occurs.
You can always call XMLNode.print() to serialize the value of a node and it's children into a PrintWriter that wraps a StringWriter to get the string equivalent of the properly escaped values.

Image Capture and special characters in file names.

Hung up image capture yesterday: We tried to enter a date in the file name of the document we were scanning. It proceeded normally, but then did not save the file and image capture would not scan again until OS restarted.
Problem repeated until we discovered a slash in the file name box. Changed the file name and everything works now.
Software should either prevent user from entering special characters in the file name box, or properly handle the error and not hang up the application.

Export Database With Password Containing Special Characters

Hi,
I'm doing a database export using the command:
exp userid=user/pass@instance parfile=exp_parms.dat
The problem is that the password contains special characters so the command fails with a syntax error. The command works perfectly fine when I run it without the password and just type it in when prompted, but I need to include the password in the command because I am running it in a batch file. I've tried using the escape character (\), but this results in a username-password mismatch.
Is there some way of declaring a password containing special characters in the 'exp' command?
...Thanks in advanced!

Hi,
I'm using linux and this is how I did it.
I created a user named ddg with a password ddg)ddg
I did my expdp command like:

Put the password in double quotes and escape the funny character with a \
Hope this helps.
