filename argument previously accepted an ASCII text string, but now accepts a Unicode text string.
LISPSYS system variable controls which AutoLISP engine is used and the behavior of the function.

Note: After the value of the LISPSYS system variable has been changed, AutoCAD must be restarted for the change to take affect.
