WinXP, RCP and Unicode/UTF-8 Labels [message #456652]

Hi,

I'm using UTF-8 as default text file encoding in my RCP application.

All my UTF-8 labels look fine as long as the application gets started inside the Eclipse IDE - but as soon as I'm exporting it as a standalone product, all special UTF-8 characters like german umlauts get lost (the labels are showing typical "wrong codepage artifacts") when running the application.

I tried to set the properties file.encoding and sun.jnu.encoding (VM Arguments -Dfile.encoding=UTF-8 -Dsun.jnu.encoding=UTF-8) but the problem remains.

Which settings do I need to get the correct "inside Eclipse IDE" behaviour?

Regards,

Robert

The strings are UTF-8 in the class file. But there is no implicit conversion to cp1252 when the labels are shown by the standalone rcp application.

file.encoding and sun.jnu.encoding (you see them in the about view - configuration) don't seem to matter either. :-(

Any help appreciated. :-)

The following snippet does the conversion UTF-8 -> CP1252 correctly (Standalone SWT application). The same label in a standalone RCP application doesn't.

package org.eclipse.swt.snippets;

import org.eclipse.swt.SWT;
import org.eclipse.swt.layout.GridLayout;
import org.eclipse.swt.widgets.Display;
import org.eclipse.swt.widgets.Label;
import org.eclipse.swt.widgets.Shell;

public class SnippetUml {

public static void main(String args[]) {

String myUmlaut = "\u00C4";

Display display = new Display();
final Shell shell = new Shell(display);
shell.setLayout(new GridLayout());
Label label = new Label(shell, SWT.NONE);
label.setText("A Umlaut (Ä) looks like: "+myUmlaut);

shell.open();
while (!shell.isDisposed()) {
if (!display.readAndDispatch())
display.sleep();
}
display.dispose();
}
}

The trick is to start the Eclipse IDE using the same file.encoding as the java editor uses:

eclipse -vmargs -Dfile.encoding=UTF-8

AND

Window -> Preferences... -> General -> Workspace -> Text file encoding -> Other -> UTF-8

When you export your RCP application then, the UTF-8-labels are displayed correctly. There are no special VM arguments needed to start the RCP application.

With this, you can share UTF-8 source code between Linux and Windows Eclipses.

Regards,

Robert
