It seems like gretl can't import cyrillic symbols (cp1251 code page) into the variable description field, anywhere else it's ok.
gretl 1.9.4cvs (build date 2011-04-11).

Could you post an example SPSS data file?
Yes. Please see here:
Thanks for posting the sample file.
There's an encoding field in SPSS sav files, but we weren't using it.
That's now fixed in CVS and snapshots.
