I don't know for sure, so I waited to see if someone else could help but
since no one has here's my thoughts....

Since you named the package "LAA" try...
   &LAA::LAA("Open");
   $abc = LAA::LAA("convert","ã¶ìØäJî‚");
   &LAA::LAA("close");

Other thoughts, in case the previous suggestion doesn't work...
  - Try putting the "LAA.xcmd" file in the "lib" folder
    contained in the MacPerl folder to make sure MacPerl can find it.

  - Are you sure "LAA.xcmd" is the exact name?
    I seem to remember that case matters.
    I think the ones I've worked with ended in ".XFCN" rather than "xcmd".
