see the setFont method. What chars are supported depend on the font
chosen. See http://mindprod.com/applet/fontshowerawt.html

Hi Roedy

I have lake an little Applet. I could not see \u015F caracter with
java.awt.List.

For the little that it is worth, I observed
the same basic behavior you describe. The
character showed in the TextArea, but not
the List, with a variety of the basic Font
types.

One possible fix is to exchange the List for
a (shock horror) javax.swing.JList. This
might work OK - *IF* the GUI does not have
items which might overlap the JList, notably
menus or tooltips.

It is a bit of a kludge, but it might work for
a temporary fix.

Have you checked the bug database? If it is
a bug, I suspect Sun's motivation to fix it
will be low. Their concentration on server
side Java, with the rest of most of their
interest focused on new classes (like
Desktop) and Swing components, would leave
very little time for them to look at
problems with AWT components (I suspect).

Or perhaps it is time to update the entire
application to Swing.

Out of curiosity. What does the app. do?
(If it is not a state secret.)
<half in cheek>
Is it something that could even be done
as a web interface?

Hi,


With this applet Customer could create their own screen and add
component.

Hi,

Could my signed Applet make an System.setProperty("UTF-8") ?

Regards

 

[Andrew Thompson]

Could my signed Applet make an System.setProperty("UTF-8") ?

No, not even an application can. There is no
System.setProperty(String) method.

 

[phil89]

Hi,

Sorry, That's ok when i launch from an Application but not from an
Applet.
My Applet is an signed applet
System.setProperty("file.encoding","UTF-8")

It may be with AWT. See http://mindprod.com/applet/fontshowerawt.html
for AWT.

If you use a canvas you can use a broader set of fonts. If you use
Components you are limited to the logical fonts.


and http://mindprod.com/applet/fontshower.html for swing

SansSerif = new Font ("Dialog", Font.BOLD, 14);
SansSerif = new Font ("Arial", Font.BOLD, 14);

You can't use Arial in AWT, only the logical fonts. See
http://mindprod.com/jgloss/logicalfonts.html

Use Swing and JList to get at all the fonts.

Try it. The worst that could happen is your code would be ignored.
