Zhang Peng's PDF; it contains a chinese font

With the attached PDF, (supplied by Zhang Peng for another purpose)
      http://lists.freedesktop.org/archives/poppler/2008-November/004216.html 
pdftohtml  fails to set the <title> tags correctly, resulting in invalid UTF8 bytes  <FE><FF> .

Within the "Document Outline" section, both entries start this way, with the first
being followed by more garbage.

This can be seen at the URL stated for this bug report:
     http://www.maths.mq.edu.au/~ross/poppler/ZhangPeng/readme.html
(You may need to set the encoding manually to UTF8.)


Facts:
-----
The document contains chinese characters, with the following font info:

<</Subtype/Type0
/DescendantFonts 33 0 R
/BaseFont/AdobeSongStd-Light
/Encoding/UniGB-UCS2-H

There is no embedded CMap resource:

Observations:
-----------
    (see also  http://lists.freedesktop.org/archives/poppler/2008-November/004220.html)

     pdftotext  worked fine for me,
       both with Poppler v0.8.2  and  Poppler v0.10.0

   However there were problems with  readme.pdf
   when using other software.

   e.g.,  Adobe Reader v8.1.0 and v9.0.0
       both showed just blank pages;

        Adobe Acrobat Pro v8.1.2
       displayed the PDF just fine

        Preview (MacOS X, v10.4.11)
       displayed the PDF just fine


   pdftohtml  translated the PDF to a 2-page HTML, with frames
       *but* there were some errors.
