Java: How to write “Arabic” in properties file?

Question

I want to write \"Arabic\" in the message resource bundle (properties) file but when I try to save it I get this error:

Properties-based resource bundles must be encoded in ISO-8859-1 to use the default loading mechanism, but I have successfully used this code to allow the properties files to be encoded in UTF-8:

private static class ResourceControl extends ResourceBundle.Control {
    @Override
    public ResourceBundle newBundle(String baseName, Locale locale,
            String format, ClassLoader loader, boolean reload)
            throws IllegalAccessException, InstantiationException,
            IOException {
        String bundlename = toBundleName(baseName, locale);
        String resName = toResourceName(bundlename, "properties");
        InputStream stream = loader.getResourceAsStream(resName);
        return new PropertyResourceBundle(new InputStreamReader(stream,
                "UTF-8"));
    }

}

Then of course you have to change the encoding of the file itself to UTF-8 in your IDE, and can use it like this:

ResourceBundle bundle = ResourceBundle.getBundle(
    "package.Bundle", new ResourceControl());
