Jennifer Hodgdon commented on FOP-2728:
---------------------------------------

One other note. The standard DocBook XSLT for converting DocBook to FO XML puts the \
language attribute on both the fo:root element and in fo:page-sequence elements, and \
possibly elsewhere. I had to remove it from all places from our actual intermediate \
FO file, in order to get the font working correctly.

So it is not as simple as overriding just one XSLT template. You have to override \
many many templates, unfortunately. This is really not a viable solution for us, as \
we don't want to have this many customized templates to maintain. I am instead going \
to either (a) wait for this issue to be fixed or (b) try a non-FOP method for \
building PDF files from DocBook, at least for Farsi.


> Persian (Farsi) output problem with FOP
> ---------------------------------------
> 
> Key: FOP-2728
> URL: https://issues.apache.org/jira/browse/FOP-2728
> Project: FOP
> Issue Type: Bug
> Components: renderer/pdf
> Affects Versions: 2.1
> Environment: Ubuntu 16.04 with xmlto 0.0.28
> Reporter: Navid Emami
> Labels: drupal
> Fix For: 2.1
> 
> Attachments: mkebooks.sh, pdf-farsi.xsl, sample-output-final.zip, \
> sample-output.zip, simple.fo, simple-nolang.pdf, simple.pdf 
> 
> We are having trouble making Persian (Farsi) language output with FOP.
> We are using the *xmlto* script with the --with-fop option to convert a DocBook \
> file to PDF using FOP, which uses XSLT to first make a FO file, and then FOP to \
> convert to PDF. We used the --noclean option to capture the intermediate FO XML \
> file. We have verified that the Persian (Farsi) characters are readable in the \
> DocBook and FO files. However, when we generate the PDF, the output is not \
> readable. There are both _joined_ and _separated_ letters in Persian (Farsi) \
> language but the output in PDF format has just separated ones. Note that there are \
> some font issues in the PDF output as well -- missing glyphs -- those show as # \
> characters, and are in the chapter/section headings. However, the main body of the \
>                 text has no # characters, and it still has this problem.
> *Attachments:*
> * sample-output.zip contains small.docbook, small.fo, small.epub and small.pdf. The \
>                 final output of PDF should be similar to EPUB.
> * sample-output-full.zip contains guide.epub and guide.pdf which are the complete \
> documents but with wrong rendering of characters in PDF.
