Dear Suzuki,
I see. What software translating from PDF to HTML
you're using? Could you post (or upload to any web
site) a sample PDF that you have some issue?
We are using Argus software for PDF to HTML conversion to create the ePUB format. All the Unicode character will not be supported by ePUB. For that, we required some of the Unicode character as an image. To avoid manual process, we are
planned to extract the character as an image at the time of extraction itself. Argus is having the features to remap the character (Eg. xFB03 =ffi;, xFB03 =<img src="" in the conversion stage.
We have successfully extracted the character as an image using one of the samples (example2.cpp) provided in the Freetype site. But after extraction there is no difference between (comma & right quote). We have taken comma & quote
right for example only.
Please provide the option to extract the expected output.

OK. I think there is not special manner specific to
this list, the clarification of input, process and
output is important in any mailing list of open sources.

Basically, an elementary font object in PDF (a data
segment which you spliced from PDF and pass to
FT_New_Face()) is not expected to hold an interface
to character encoding. For the relationship between
glyph index (or glyph name) and the character code,
/Encoding or /ToUnicode elements in wrapping font
object in PDF (which refers its elementary font object
via /BaseFont object). Referrer's /Encoding dictionary
can override the built-in encoding info in the referred
font.
I think there are existing softwares like pdftohtml
which do such work in good level.

As I've written in above, extacted font file is insufficient
resource to guess the codespoint for the glyphs.

Do you say that your program (at present) cannot detect
the character code point for the single quote glyph and
the comma glyph from PDF, then you want to guess the
codepoints by checking the indepth of the font?
Does Adobe Acrobat extract the text from your PDF?
