'Unicode' is a not an encoding. As the help says
fileEncoding: character string: if non-empty declares the encoding used
on a file (not a connection) so the character data can be
re-encoded. See the ‘Encoding’ section of the help for
‘file’, the ‘R Data Import/Export Manual’ and ‘Note’.
The first of the cross references explains this.

A colleague is sending me quite a few files that have been saved with MS
SQL Server 2005. I am using R 2.15.1 on Windows 7.
See the posting guide: your R update is overdue as there have been 5
releases since then.
I am trying to read in the files using standard techniques. Although the
file has a csv extension when I go to Excel or WordPad and do SAVE AS I
see that it is Unicode Text. Notepad indicates that the encoding is
Unicode. Right now I have to do a few things from within Excel (such as
Text to Columns) and eventually save as a true csv file before I can
read it into R and then use it.
Is there an easy way to solve this from within R? I am also open to easy
SQL Server 2005 solutions.
I tried the following from within R.
testDF = read.table("Info06.csv", header = TRUE, sep = ",")
testDF2 = iconv(x = testDF, from = "Unicode", to = "")
Error in iconv(x = testDF, from = "Unicode", to = "") :
unsupported conversion from 'Unicode' to '' in codepage 1252
# The next line did not produce an error message
testDF3 = iconv(x = testDF, from = "UTF-8" , to = "")
testDF3[1:6, 1:3]
Error in testDF3[1:6, 1:3] : incorrect number of dimensions
# The next line did not produce an error message
testDF4 = iconv(x = testDF, from = "macroman" , to = "")
testDF4[1:6, 1:3]
Error in testDF4[1:6, 1:3] : incorrect number of dimensions
Encoding(testDF3)
[1] "unknown"
Encoding(testDF4)
[1] "unknown"
This is the first few lines from WordPad
