IndexOutOfBoundsException when translating English to Arabic BETA

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Write the following code in a JSP:

if(request.getParameter("textToTranslate") != null 
    && request.getParameter("textToTranslate").trim()!="") {
        String textToTranslate = request.getParameter("textToTranslate");
        String translatedText = Translate.translate(textToTranslate,
Language.ENGLISH, Language.ARABIC);
        out.println(translatedText);
    }

The JSP must be passed some Arabic text from another page as form fields.

2. Run the page.

What is the expected output? What do you see instead?

The expected output is a page that has the Arabic Translation. It shows an
empty page with the following exception:

I am using version 0.2 on Windows XP and running the web application on
Tomcat v5.5.

I've added a new version, 0.21, with a fix for languages that read from right to
left. It shouldn't throw a null pointer now but I'm not sure whether the 
encoding
will be correct. I'll look into it further later.

You are right as it may have some encoding problems. I tried translating "How 
are
you" with the 0.21 API and the good thing is that there were no exceptions but 
still
the output is bad.

Please see the screenshot.

Thanks for your help on this Zab. I've released 0.22 which should work 
correctly now.
