Yes, older software like spss.get needs to get updated for the 
internationalization age.  Modifying it to have a ... argument passed to 
read.spss would be a good idea (and future-proofing).

In cases like this it is likely that the SPSS file does contain its 
encoding (although sometimes it does not and occasionally it is wrong), so 
it is helpful to make use of the info if it is there.  However, the 
default is read.spss(reencode=NA) because of the problems of assuming that 
the info is correct when it is not are worse.
