Did you test the same thing with another program using iconv?

I've encountered the same problem in iconv when I tried to convert an
ISO-8859-1 string containing "~" to Shift_JIS. Shift_JIS actually
does not define the tilde character, so iconv bailed out and returned
an empty string (the solution is using codepage 932 instead when
people ask for Shift_JIS. Bleh.)
