Creating Multi-lingual Application

[eluser]bigdaddysheikh[/eluser]
Hey Guys,

I am working on this project that requires multiple languages such as chinese, arabic, farsi, polish etc... How is this handled by the database and how do I display the output? Since these languages are not system fonts, is there anything I can do programming wise to instill that the language stays the one selected rather than english.

Any light on this topic would be greatly appreciated.

Thanks in advance.
