[Swftools-common] Help on problem converting Chinese PDF to SWF using pdf2swf

[Jeff Tang]

Hi,

I've been testing with pdf2swf for the past few days, and overall it's a great tool. But I've been struggling with some pdf files that have Chinese content, here's the message I got:

NOTICE  processing PDF page 1 (499x719:0:0) (move:0:0)
WARNING The following font caused problems:
WARNING =========== STSong-Light,Bold (ID:17,0) ==========

WARNING Didn't find character 'NULL' (c=3855,u=24687) in current charset (Times-Roman, 316 characters)

My system doesn't have the STSong-Light,Bold.ttf file, but what does the warning about Times-Roman mean?
What's confusing to me is that I can successfully use pdftotext, a tool in xpdf, to convert the same pdf file to
text, extracting the Chinese content correctly. I use "pdftotext -enc GBK test.pdf test.txt".

What could be the problem? Your help would be greatly appreciated.
