Can anyone out there answer this question?
I ended up giving up on compiling wkhtmltopdf to fix this problem:
What I did instead is using Apache's PDFBox java library and loaded the PDF generated from wkhtmltopdf and removed the "#00" characters.
But I would love to re-compile wkhtmltopdf v0.11.0.rc1 again some how because it seems to generate correct PDFs. Re-compiling wkhtmltopdf with latest patched QT versions seems to yield PDFs with bad layout.
