Hi Randy,

Thanks for the pointer to the shapefile. I've done some more testing at this
end, and I believe that the problem you are seeing is not related to
libiconv-2.dll as I see exactly the same error message on a fresh Linux
install as well as Windows. The complete list of encodings is given in the
iconv documentation
(http://www.gnu.org/software/libiconv/documentation/libiconv/iconv_open.3.ht
ml). I had a look around the www.census.gov website and unfortunately it
doesn't give any information about the encoding of the provided shapefiles
:(

Since this is reproducible on Linux as well as Windows, I'm inclined to say
that it's an encoding mismatch rather than a Windows build error. However I
notice in your original post that you managed to use a Java program to do
the conversion for you. Unfortunately I'm not the world's greatest expert
when it comes to locales and encodings - can anyone else help out here?


Kind regards,

Mark.
