Running on a Sun Ultra 5 running Solaris 7:

leprss% perl !$
perl test_encode.pl
encode_qp( ä ) = =8A

Running on Yellow Dog Linux:

linux% perl test_encode.pl
encode_qp( ä ) = =8A

I suspect you transferred the file in such a way as to change the 
encoding of ä.  (Did you email it to yourself?).  The character code 
that stands for ä is likely to be different on Linux than on MacOS. 
I simply pasted your script into a terminal window, so no translation 
was done, and it still looks like an ä to me on my iBook.  I suspect 
it will look like something else tomorrow when I'm at the Sun's 
console.
