That doesn't look like output from podofotxtextract. Are you sure you're
not using ContentsTest instead?
Here's what I get from podofotxtextract for "chinese.pdf":
C:\Developer\build\podofo-msvc2008\tools\podofotxtextract\Debug>podofotxtextract
.exe "C:\Documents and Settings\c\Desktop\chinese.pdf"

PoDoFo encounter an error. Error: 2 ePdfError_InvalidHandle
Error Description: A NULL handle was passed, but initialized
data was expected.
Callstack:
#0 Error Source:
..\..\..\..\podofo\tools\podofotxtextract\TextExtractor.cpp:104
Information: Cannot create font!
So as you can see, it's having trouble understanding the font. Not sure
why yet, I haven't looked into it.
I actually get a crash of podofotxtextract when reading sample3.pdf .
Unsure why yet, I'm looking into it now.
