PDF417 standard has no idea about unicode. The standard defines a feature called Global Label Identification (GLI), which is supposed to sort out mixed language issues. However, it is still single-byte based and requires that the application(or the scanner) handles the translation issue.
If you have the control over both read/write, you might consider a straightforward solution - just treating unicode/arabic characters as binary. Your application handles the translation at both sides.
