well, encoding issues tend to confuse me, badly. However, here are some ideas:

- To narrow down the problem, it's always a good idea to try in plain R, or in 
this case, in the plain Rgui.exe (also included in the installation bundle). 
If there is any difference between plain R and RKWard, be sure to also check 
for differences in Sys.locale().

- Writing R Extensions has a section on encoding issues: http://cran.r-
project.org/doc/manuals/R-exts.html#Encoding-issues . I'm not really sure, 
what to make of that, but I guess the best hints in there is to play with 
Encoding() (and possibly with enc2native()), and to check the "Encoding" field 
in the package's DESCRIPTION file.

- I did not understand, how exactly you pass text to / from the external 
commands. If this involves writing to text files as an intermediate step, then 
of course it may be instructive to check the encoding of those intermediate 
files.

Hope that helps a bit.

Regards
Thomas
