Yes, that is the font I am using in my Word file. Please check the following files. Thanks.

Assuming you mean, http://www.microsoft.com/typography/fonts/family.aspx?FID=375 - I can easily install it.

Just post the files on your favorite sharing site and post the links.

the original document? I don't know if you have installed Sakkal Majalla font in your system or not. Otherwise you can't correctly display the docx file. Can I attach a PDF and a Word file in reply?

Most PDF production tools will not include the GSUB table in the embedded font because it's not required by the spec and not used by the renderer. So you shouldn't expect to find that.

Don't know - I'd need to see the original document and then final PDF to understand.

I thought maybe I could get some information from Truetype font tables which are stored in FontFile2 of FontDescriptor, like GSUB and CMAP. Or I could get some information from those PDF objects which I didn't know to recover an incomplete cmap. I know it is impossible now.

I used the "Create PDF" button to export a PDF file. The toUnicode becomes incorrect. CID 0284 and 06B4 have the same unicode U+FFFD. What happened?

Ah - misunderstood the question.

If the mappings aren't provided in the ToUnicode, then you COULD go back to the font (but doing so is outside the spec) or you fallback to the notdef glyph/encoding (as per spec).

I developed an app to extract texts from PDF. I can't decide how my customers generate them. Do you mean there is not any solution to solve my question?

BTW, there are only the following tables in FontFile2.

Printing to PDF is the worst way to get extractable text - since a printer doesn't need that information and the app won't send it.

Instead, just use the "Create Adobe PDF" button that is installed in Word for you by your Acrobat installation.

I printed a Microsoft Word file as a PDF file by Distiller with an embed SakkalMajalla truetype font. I want to extract unicode texts from the PDF file. I found ToUnicode misses part of mapping. For example, CID 06B4 doen't have any mapping. I guess 06b4 should be mapped to U+0644. There are some substitutions in SakkalMajalla. So uni0644.medi (U+FEE0) is replaced by liga.0758.medi.alt1 (U+10354). Why can't Distiller deal with the situation? How can I recover missed mapping from PDF objects except ToUnicode? Thanks

P.S. I also asked the question couple days ago. Please see Re: Is it a bug of Distiller? I haven't got answers. I don't have privilege to move or delete that discussion. Sorry for asking a question in two communities.
