No, these error messages are quite normal. Greenstone's PDF and Word plugins
always force the use of UTF-8 because that's the output encoding used by the
pdftohtml and wvWare programs used by the plugins to convert these formats
to HTML. When the converted HTML files are passed to HTMLPlug it sometimes
complains because it attempts to detect the encoding for itself and gets it
wrong.

Anyway, it should be safe to ignore these messages.

Maybe it's a size thing or maybe it's just a PDF that was created in some
way that pdftohtml can't handle. Try running pdftohtml on the PDF directly
from the command line. That may give you more of a clue as to why it's
failing. There's also a newer version of pdftohtml available from
http://pdftohtml.sourceforge.net. You could try downloading the new version
and seeing if it's any better at converting your problem document.

Good luck,
Stefan.
