excel doest it support arabic language

Dear All,
i run hello Excel example and it works perfectly what i face it now is that The excel file still not appear language arabic?Is there any encoding feature or support for other languages rather than english

Thanks to all

Which library's "hello excel" example is that?

What does "still not appear" mean - did you change something, and expected different output as a result? If so, what did you start with, what did you change, and what was the result you got?

arabic letters appear like rubbish letters=E9/D 'DE4'1C) 'D'B*5'/J) 'DEFB-
what i expect is arabic letters(Not latin charachters)
with english letters it appears perfectly.
Note: the arabic letters(sentences) come from Oracle DB and it appears perfectly at jsp pages.

POI assumes Unicode encoding - is that what the characters are in?
