PDF that causes pdftohtml to produce invalid XML

On certain PDF files the pdftohtml utility run with '-xml' option produces XML
that is invalid and cannot be parsed by strict compliant parsers.

Test case:
# wget -q http://www.tml.tkk.fi/Studies/T-110.557/2002/papers/burlacu_mihai.pdf
&& \
    pdftohtml -xml -i -c -f 1 -l 1 -noframes burlacu_mihai.pdf x && \
    python -c 'from xml.parsers.expat import ParserCreate;
ParserCreate().ParseFile(open("x.xml"))'

With pdftohtml's versions 0.6, 0.10, 0.12 and python version 2.5 it produces:
Page-1
Traceback (most recent call last):
    File "<string>", line 2, in <module>
xml.parsers.expat.ExpatError: not well-formed (invalid token): line 45, column
63

The offending byte is an ASCII control byte (0x11). It's followed by other
ASCII control bytes.

I attached the burlacu_mihai.pdf for reference here in case is becomes not
available on the original server. I'll contact the copyright owner for the
acknowledgment and will remove this file in case the author doesn't allow
redistribution of the file.
