How to define and use special characters

I need to define some special characters (such as an up-arrow and a down-arrow). I need to add these characters to Strings along with "normal" ASCII characters, and finally display the Strings with graphics.drawString().
Can anyone get me started or tell me where to look? I looked at the archive but apparently I'm not using the correct keywords.
Thanks in advance, Rick

public void paint(Graphics g) {
        super.paint(g);
        g.drawString("up arrow: \u2191 down arrow: \u2193", 100, 100);
    }Works for me.

Connect to SAP BW and using special characters in password is not working

Hi guys,
I connect to a SAP BW System. When I'm using the special character & in my password, I can't connect as the universe designer says that I entered the wrong password. If I remove the special character the connection works and I can select a query.
Is this a know bug? What can I do?
Regards,
Christian

Hi Christian,
According to my knowledge this is not a know issue.
I recommend you create a support case in order to have your issue fixed.

Use special characters in a DTD

Hello,
I created a DTD amd want to use some special characters in this DTD. E.G. I want to define:
<!ATTLIST element value (val1|val 2|<val3>|%val4) #REQUIRED>
I tried the following but the parser does not accept without errors:
<!ATTLIST element value (val1|val&#xxx;2|&#yyy;val3&#zzz;....
Of course I replaced the xxx, yyy and zzz with the unicode number of the special sign.
So what do I do wrong? Or is it in general not possible to use special characters ?
Thank you very much,
Findus

Hi,
one thing I did which does not work is:
<!ATTLIST element values (&|<|val1) #REQUIRED>
The XML parser (XMLSpy) alway requires me for entering a '%' which is as far as I know only used for parameter entities. But & and the rest are general entities, aren't they ??
I played arround a little bit and found a solution which still does not completly solve my problem: In order to use special characters I declare parameter entities:
<!ENTITY percent "%">
<!ENTITY lower "<">
<!ATTLIST element values (%lower;|val1|%percent;) #REQUIRED>
This works so far so good but if I want to embed the special characters (which is what I need to do!) the parser still gives me errors:
<!ATTLIST element values (text%lower;moreText|val1|%percent;) #REQUIRED>
I would be really glad if anybody could test this on his own and post me about the results. For any other kind of avice I'm very thankful, too.
Thank you very much,
Findus

E72: Swedish and other special characters not work...

When I send mail through MfE, swedish and other special characters do not reach the recipient, they are just ignored. No blanks or nothing. Every word with a swedish character ends up one letter short.
Before the firmware upgrade this was intermittent, happening only on about half of my mails.
Now I upgraded yesterday, and it seems the problem is now permanent.
Have seen similar posts from E75 and E90 owners, their problems seem to have been fixed by newer firmware.
Our setup is: Exchange 2003, Portwise authentication.
All other phone models work fine, like iPhone, E71 etc.
/Sebastian

After some testing I found out that if I use swedish chars in the subject line, it works fine. Even in the mail body.
If I don't use swedish chars in the subject, they won't work in the body. I either get garbage or nothing where the swedish chars should be.
The problem doesn't exist at all in my private IMAP mail account.
Could someone who uses Mail for Exchange and have special chars in their alphabet (swedish, finnish, german, hungarian etc) pls tell me how it's working out for you?

Using special characters (Spanish characters) in Activities name

Hi everyone,
?:| Does anyone knows if I need to do any extra configuration in my Operating System/Data Base if I'm using special characters (accents) in activities/transitions name. Is there any problem using these type of characters?
Thanks a lot.
Edited by varriaga at 01/04/2007 2:17 PM

in ALBPM 5.7 you don't need any specific setup to use spanish characters, since we store all information as NVARCHARS.
In Studio, we store projects files in UTF-8, so no problem either.

PS: you are just asking or you do have a problem? if you do, contact support and describe your problem.

Capturing returns and other special characters

Greetings,
I'm curious to know what is 'normally' done to capture
returns and other special characters from textareas. I want my user
to be able to insert 'control' characters into the text area to
allow them to provide some structure to the information they're
entering. At the moment, I'm processing the text char by char and
working out if it's an 'enter' or whatever, then appending a
'<br />' to the string before I store it and so on.
Is there a more established way to do this sort of
thing?

Use the replace function to replace either chr(10) or chr(13)
with a break tag. It's using cold fusion functions to accomplish
the same thing you appear to be doing manually.

With session.setAttribute("name",object) you can store a Attribute in the session object.
with session.getAttribute("name") you can get it.
That's it.

How to install and use a plug-in downloaded from the apple site?

how to install and use a plug-in downloaded from the apple site?

Emelie,
which plug-in do you want to install?
some of the plug-ins come with an installer on the disk image, you click the installer and it will install it in its proper location.
For others you move the plug-in into to System Library or your User Library:
Your Hard disk > Library > Application Support >Aperture > Plug-Ins > Edit
or
Your Home Folder > Library > Application Support >Aperture > Plug-Ins > Edit
If it is an "Edit" plug-in, it goes into the "Edit" subfolder, "Export" plug-ins into the "Export" subfolder.
You can tell by the extension, what kind of plug-in it is.
E.G. BorderFX.ApertureExport is an export plug-in, BorderFXEditPlugin.ApertureEdit an edit plug-in.
Regards
Léonie
P.S. In OS Lion the Libraries are hidden by default: To reveal your User Library activate the Finder and select from the main Finder menu:
    Finder > Go , then hold down the ⌥-option-key, untill the Library appears in the drop.down menu.
To show the System Library:
     Finder > Go > Go to Folder
then enter   / Library
