Unicode - General OS question [message #487841]

Hi there,

The RCP application we are building will use a great deal of unicode, Armenian alphabets and what have you.

As a test, I attempted to paste the character "♀" in a SWT Text field in an instance of our application running on my Windows machine (didn't work) and then on the Mac machine of a colleague (success). I can paste it successfully in Word, Firefox, etc. on my Windows.

Note that this has (as yet) nothing to do with using unicode in a file being edited - hence, the VM arguments "-Dfile.encoding=UTF-8 -Dsun.jnu.encoding=UTF-8" unsurprisingly have no effect.

What am I missing here? What determines whether an instance of an RCP application - above all its SWT Controls - can handle unicode?

Many thanks in advance,
Pepe Ciardelli

Make sure that the font you use contains that character.

Aha, indeed! Thanks very much.

The obvious followup question then: is there a way to change the default text for all controls from the default system font to something unicode-compliant in one fell swoop?

Just wanted to share what I found:

SWT controls set their font with Display#getSystemFont() and there's no way to set a different default font for all controls. Therefore, the appearance settings on Windows machines that don't have a unicode-compliant system font must be changed.

The first step is to make sure that a unicode-compliant font is installed on the user's Windows system. This explains how: http://unicode.org/help/display_problems.html.

Then do the following:

1. Right-click on desktop
2. Choose "Properties"
3. Appearance -> Advanced (this is where you want to be: http://delltech.150m.com/XP/desktop/desktop.advanced.png)
4. Item: "Message Box"
5. Font: Arial Unicode MS

After settings are updated, unicode will be visible in Eclipse applications.

Or you change your default OS font. SWT will pick that up.

Try to add the line:

-Dfile.encoding=UTF-8

to your eclipse.ini file and reboot the Eclipse.
