Just a simple check with special characters

Hi guys and gals,
i created a boolean method that will check the value of string for any special characters like (/,'%&^# ), what i did is to used indexOf() method. it will return false if the string doesn't have any special character. But, i'm having a problem using the check for the backlslach character ' \ ', since it is considered as escape literal when i put inside indexOf('\'). i really need you help on this.
if you have other ways to check this kind of character, please put them here. i really need them bady. :D many thanks,

Look for "\\" or look up the unicode for "\" and use that.

File XML Content Conversion: Problem with special characters

Hello,
in a file sender cc content conversion is used to transform a flat structure to XML. What we experiencecd is that the message mapping failed due to a character that was not allowed in XML:
I was assuming that the file content conversion just creates XML messages with allowed characters. Is there any way to configure content conversion to remove control characters which are not allowed in XML? Unfortunately the sender system cannot be modified.
Thank you.

Hi Florian,
Please use this UDF to remove special characters which prevent XML messages to form properly.
public static String removeSpecialChar(String s)
          try
               s=s.replaceAll("&","& amp ;");
               s=s.replaceAll("<" , " & lt ;");
               s=s.replaceAll(">", "& gt ;");
               s=s.replaceAll("'", "& apos ;");
               s=s.replaceAll("\"", "& quot ;");
          catch(Exception e)
               e.printStackTrace();
          return s;
Please remove spaces between characters within double quotes. I have added them because otherwise you can't see this code properly. Please check this below link , please replace the characters with proper values as the display is causing a problem here

Problems with special characters like "u00F6" "u00E4" "u00FC"

Hi,
we currently face some major problems with special characters like "ö" "ä" "ü". First I thought it is a SP02 specific problem but it still doesn't work with SP03.
When I start an import the import manager shows correct converted value. "ö"s "ä"s "ü"s are displayed correctly. But after I've done the import I look into the Data manager and I see instead of these characters charcaters like "̈". (note: the character should show a little square box - but the forum cannot desplay it)
How can I solve this problem?
Regards
Nico

Hi Nico
Just try it out the following steps, hope it solves ur issue.
<b>To set one or more values back to their original values:</b>
1. In the Import Manager Source Values grid, select the values that you want to set back to their original values.
2. Right-click on one of the values and choose Set to Original Value from the context menu, or choose Values > Apply Value Conversion Filter > Set to Original Value from the main menu.
3. MDME sets each value back to its original value, which appears in black in the Source Values grid.
<b>NOTE : You can use the Set to Original Value filter only at the value-level and not at the field level.</b>
thanks

Problems with special characters in JSP app

Hello!
I am working for a JSP application which uses special characters.
The database used is a Novell MySQL version, it is fine.
I use Tomcat, Apache.
I do not think that the versions are important.
ON NT:
The application works fine with special characters.
Obs: I tried only with Tomcat; I didn't use Apache.
ON NOVELL:
If I try to insert some special characters,
they arrive just fine into the database.
The problem is when I want to display them.
I tried with jsp directive to set the charset,
or with HTML meta tag - no result al all.
Everytime I use the same work station, and the same browser to do the tests.
Please help with any ideas.
Another question, maybe relayed:
Can I set Tomcat so that when it creates the servlets it uses a custom charset I can indicate?
THANK YOU!

The characters I want to use are french characters, e-acute, etc.
I take the data with request.getParameter, POST method, etc.

Problems with special characters in InputStream or XPath

Hello everyone,
I am having problems with special characters such as ", ', - and so on, everything becomes ? (questionmark). (Not with special nordic characthers (å,æ,ø) though.)
The encoding of the XML is UTF-8, and the server that holds the webservice is setting encoding to UTF-8 also, so no conflict there.
What I have done is something like this:
{code}
String url = "http://www.formula1.com/rss/news/latest.rss"; // This is not the feed I use, it is a custom XML document
InputSource is = new InputSource(url);
DocumentBuilderFactory fct = DocumentBuilderFactory.newInstance();
DocumentBuilder builder = fct.newDocumentBuilder();
Document doc = builder.parse(is);
Element rootElement = doc.getDocumentElement();
XPathFactory factory = XPathFactory.newInstance();
XPath xPath = factory.newXPath();
out.print(xPath.evaluate("/rss/channel/title", rootElement)); // The xml is not a RSS feed, this is just an example.
{code}
Please let me know what I am doing wrong, or give me a hint of how to solve this in another way.
Best regards,
G.Hansen

Hello, thanks for you reply. I had to rewrite your code a little, and I think that your code would not really compile, if you tried yourself :-)
I ended up with something like this:
our environment is running in 1.4 mode, so I could not use the for-each loop :-(
public String printEntities(String s) {
     char[] sArray = s.toCharArray();
     StringBuffer sb = new StringBuffer();
       for (int i = 0; i < sArray.length; i++) {
         if (sArray[i] > 256)
              sb.append("&#x" + Integer.toHexString(sArray) + ";");
     } else
          sb.append(sArray[i]);
     return sb.toString();

Problem figuring out the encoding for filenames with special characters

I'm not sure if this is the right forum, but this does seem like an OS issue.
I brought in a lot of mp3 and m3u files from a Windows machine to my new Mac. Some of the mp3 files have accented characters in their names, and these names appear in the m3u files. But if I add the m3u file to iTunes, it fails to recognize these names and so I lose all the mp3's with special characters in their names.
I tried to fix this by grabbing the files name in Python, but that didn't work either!
Here's an example: the file's name is "Voilà l'été.mp3"
The m3u files says "Voil\xe0 l'\xe9t\xe9.mp3" -- this doesn't work.
From os.listdir(), I get Voila\xcc\x80 l'e\xcc\x81te\xcc\x81.mp3", but sticking it in an m3u files doesn't work either. (Note that here the characters are encoded as unaccented letter + two byte code for the accent).
When I try these strings from python, e.g. doing os.stat(), they both work; but iTunes doesn't understand any of them!
I'd appreciate any hints on how to enter these names in the m3u file so that iTunes can read it. Thanks!

I know nothing about "m3u" files and how iTunes interprets the file names in them, but if it is not a relative/absolute path problem, then how about just putting the raw file names (not the ones with backslash escape) in m3u file? For example, just put
Voilà l'été.mp3
in m3u?
As for Unicode encoding, HFS+ file system uses the "decomposed form" for accented characters. This means, as you write, à is hex "61 cc 80" in UTF-8, i.e., "a + COMBINING GRAVE ACCENT". The pre-composed form is hex "c3 a0". But my experience is that in most cases both pre-composed and decomosed forms work at the user level (not at the lowest file system level).

Tabular model column rename with special characters - ), *, /, +, %, [ etc

I am working in tabular model 2012. I have requirement to rename the column names with special characters like ), *, /, +, %, [ etc. When I try to rename in my model, it gives me below error:
I also tried renaming the columns after creating a new test model with no luck. I may have lived with this error however we have another tabular model which contains special charaters in the name. This makes me believe that there must be some setting that
I am missing.
I tried changing the column name in other model having some special characters and it takes it.
I have gone through this link#

and
http://msdn.microsoft.com/en-us/library/gg492144(v=sql.110).aspx which says that special characters are not allowed in column names however I am able to do it in one of our
models then why not others.
Any help is appreciated! Thank you for you time.

Well Mr. Google helped me.. I got the solution:
Databases of a specific modality and compatibility level can have object names that include reserved characters. Dimension
attribute, hierarchy, level, measure and KPI object names can include reserved characters, for tabular databases (1103 or higher) that allow the use of extended characters.
How to change the compatibility, just right click on the .bim file from SSDT and go to properties and change the compatibility to 1103.
I hope this will help someone. :-)

In my program, on the selection screen a user can enter any variable except special characters.How can I put a check on special characters??

hi,
In our key board, these many special characters present..
so try your code like this..
data: spe_char(31) value '~`!@#$%^&*()_+-=\|][{}";:,./?><'. ( include all
special chars whatever u want)
spe_char1 value ' '. ( this is to check empty space)
spechar2. (this is to check single ' ).
Create one text element and assign ' as value to that text element.
in ur program code as given below.
spechar2 = text-001.
if (fieldname) CA spe_char.
MESSAGE "special character is present in the given input
endif.
if ( fieldname) CA spe_char1.
message "special character is present in the given input

SSID with special characters showing up in place of the letters

On a Win 7 machine the SSID list of available wireless networks is showing up with special characters in place of the normal letters in the name of the SSID... It has nothing to do with the Linksys Router, it is a problem on this computer. It makes it impossible to connect to a wireless network. I removed the device and reinstalled it hoping that might help. I can't find any viruses, (Known Viruses) Has anyone here seen this before? I am atttaching a photo of this. Any help appreciated.

Is this the only computer having a problem? How many wireless devices are connected and working to the router right now?

Problem with special characteres

Hi. I have a problem with java. I�m making an application that works with special characters and displays correctly on my local machine, as I use escape characters such as ì for �. The problem is when I deploy the application on a unix machine. All of the special characters (�, �, �, etc) appear like a �?� (question mark). Any tips, please?
Thanks in advance

Any tips, please?First step: read [this excellent introduction into Unicode|http://www.joelonsoftware.com/articles/Unicode.html], it will give you the basics you need to solve this problem.
How do you input and output those characters? Simply print them to the console? Or write them to a HTML file (since you mention &<something>; notation)?
"?" is normally the result when you convert a String (which is always in UTF-16 encoding in Java) to an encoding that can't represent your characters (ASCII for example).

Tag Query with Special Characters in Tag Name not working

Hello-
We are on SAP xMII 12.0 sp8.6, connecting to Honeywell's PHD. We are doing Tag Queries, and all is working well, except when there are special characters in the Tag Name (+, /, \) We have attempted to do the Encoding of the tag name, such as as is returned from the function xmlencodename and also tried URL Encoding.
Here is our tag which returns nothing.
82TK1INV.OCTANE_R+M/2
We have also tried these encoded versions, still to no avail:
82TK1INV.OCTANE_R%2BM%2F2
82TK1INV.OCTANER_M_2
Any help on how to return the values with special characters in the tag name would be very helpful!
thanks,
Paul Mazeika

To Chianti's question of why can't/shouldn't MII work with those bizarre tag names...
Actually, there are a number of reasons:
1) It's a poor design practice to use characters like that in tag names, regardless of the underlying system. That type of information is best assigned to the tag description, not the tag name. I've even seen idiots put leading spaces on tag names...figure that one out!
2) MII uses XML extensively, and XML's syntax rules dictate what is and is not acceptable for XML element and attribute names, and many of these special characters are not permitted.
3) Usage of characters in tags that also represent mathematical operators greatly complicate the parsing and processing of expressions that involve tag names
In general, it reminds of the story of the guy who walks into the doctor, bangs his fist against a specific spot on his head, and says "Doc, it hurts when I do this", to which the doctor responds, "so don't do that".
So, Don't Do That.

Empty datafile with special characters in name

Hello all
I'm having an issue with an empty datafile that is in recover mode.
Previously the following has been successful :
alter database create datafile 'fully_qualified_file_name' as 'fully_qualified_file_name' ;
recover datafile 'fully_qualified_file_name' ;
alter database datafile 'fully_qualified_file_name' online;
However this time it doesnt work as I get errors :
ORA-01516: nonexistent log file, data file, or temporary file
Using the file id doesnt work either.
When I created a control file trace I can see the datafile has special characters in the name :
'/oracle/PRD/112_64/dbs/PSPR3I ^?;^?'
As it is empty, would it be possible to create anothr empty datafile
using :
alter database create datafile '/oracle/PRD/112_64/dbs/PSPR3I ^?;^?'
as '/oracle/PRD/spdata2/r3i_8/r3i.data8';
then recover datafile 'fully_qualified_file_name' ;
alter database datafile 'fully_qualified_file_name' online;
How do oracle commands cope with special characters?
Thanks for your advice

It should work using a file number as the source file definition and a new name for the new file. Works for me:orcl> alter database create datafile 7 as 'c:\tmp\newname.dbf';
Database altered.
