Font chinese and arabic

At present we are using one application , in which they are loading some files.

the files are some times a mix of chinese and arabic.

Is there any way to encode these literals and do the loading.

when we export files from DB to flat files in unix , we are facing issues such that arabic and chinese literals are converted in to proper format in flat file.
Do we have to set some encoding standards here
