R help - Jan 2010 - Reading a file with mixed cyrillic/latin characters

Dear useRs,

I am trying to read a tab-delimited Unicode text file containing both 
latin and cyrillic characters and failing miserably. The file looks like 
this (I hope it comes across right):

A	B	C
3	foo	???
5	bar	???

read.table("foo.txt",sep="\t",header=TRUE)

I am guessing that I can use the fileEncoding argument to read.table() 
to read this, but I can find no list of supported values of 
fileEncoding, and fileEncoding="Unicode" gives an error.

The FAQ and the FAQ for Windows don't help. I have searched both the 
list archives and RSeek and am still seeking enlightenment. I am running 
R 2.10.1 on Windows XP, sessionInfo() below.

Cheers
Stephan
