PDF info generation #6

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 
Currently PDF info generation is commented in code (look for 'pdfinfo').
This was due to incorrect display of non-ascii chars. Perhaps same trick as
we do for TOC UTF8 encoding would work here?

The PDF TOC trick as is doesn't work (I tried it yesterday).

I wonder if at all it is possible to have UTF-8 in PDF info? Anybody have seen 
PDF
file with russian info?

If I look into PDF file I can see:

/Author()/Title()/Subject()/Creator(LaTeX with hyperref
package)/Producer(pdfeTeX-1.21a)/Keywords()
/CreationDate (D:20070313221053-07'00')

I guess we can do a small python hack, adding author and title to already 
generated
PDF document file.

since eBook does not show cyrrilic from PDF info we will need to transliterate.
First step to develop transliteration function per:

we could use 'pytils' module
http://cheeseshop.python.org/pypi/pytils
http://code.google.com/p/pythy
The library under GPL

Here is an example:

>>> import pytils
>>> pytils.translit.translify(u"Вадим Залива")
'Vadim Zaliva'
>>> pytils.translit.translify(u"Александр Сова")
'Aleksandr Sova'

It's their own but very close to GOST 16876 (1971). These standarts are useless 
for 
us because all of them (except that 30-year old GOST) use diacritics. I do not 
think 
we want that. 
I like the algorithm implemented by 'pytils'better then GOST. it is closer to 
what 
is actually used now.

vberko just opened my eyes to new issue: SonyReaders which have been "russified"
(flashed with russian fonts) might show russian letters correctly in PDF info.
In this case we need to have an option controlling whenever generate russian on
transliterated PDF info.

Here is link about using cyrrilic in PDF meta info:

for now calls to pytils.translit.translify() added. In future we will
have an option to specify whenever to use translit or try to generate
russian info.

last workaround from trivee does not completely fix this problem. To quote him:

На самом деле надо сделать не так. То, как 
сейчас - в Sony Reader
работает, в Acrobat Reader  не работает. Чтобы 
починить правильно,
надо в пакет hyperref передать несколько опций 
(pdfauthor, pdftitle),
или не использовать hyperref.

looks like the title string we got is not a unicode string.
The document is in windows-1251 encoding. The same string works just fine with 
manual input.
I'll play with it more
