#1 Updated by Michael Pirogov about 15 years ago

They says that (http://dry.4thebusiness.com/?document=3) they've
unicode support. Check out test_unicode link and see, that russian
and all other non-latin stuff is just fine.

#2 Updated by David Fugere about 15 years ago

have you found an answer?

#3 Updated by Nikolay Solakov over 15 years ago

Can anyone solve this old puzzle?

Thanks,
Nikolay

#4 Updated by Jean-Philippe Lang almost 16 years ago

Since, rfpdf is a ruby port of fpdf, I've tried to add bulgarian
support following this tutorial:
http://www.fpdf.de/tutorials/7/
... with no result. I only get squares instead of cyrillic
characters.

#5 Updated by Nikolay Solakov almost 16 years ago

I forgot... this is in my bg.yml lang file:
general_csv_encoding: windows-1251
general_pdf_encoding: windows-1251

Thanks,
Nikolay

#6 Updated by Jan Topiński over 14 years ago

I think I've fixed that one. See bulg.pdf.

To fix it one needs to

  1. Update rfpdf to the newest version:
    script/plugin install git://github.com/edwinmoss/rfpdf.git --force
  2. Apply attached patch:
    patch -p0 < 61.patch

Pdf export worked fine for me (Polish) and for Bulgarian.

#7 Updated by Paul Rivier over 14 years ago

  • Assignee set to Jean-Philippe Lang

Hello Jan,

thank you for this patch.

Can anybody with different locales try and confirm that UTF8 export now works well.
Jean-Philippe, any position on the current status of the pdf exporter in redmine ? I see 0.8 is planed for 7 weeks from now, do you think we can integrate the updated version of rfpdf and Jan's patch before feature-freeze ?

#8 Updated by Jean-Philippe Lang over 14 years ago

I'd really like to fix it but it doesn't work for me.
Jan, after following the above instructions, pdf are broken (see attached french and bulgarian pdf). Any idea?

Paul, does the patch work for you?

#9 Updated by Ernad Husremovic over 14 years ago

I can confirm that bosnian characters works well.

general_pdf_encoding: utf8

after rfpdf upgrade, pdf size is 314 KB (attached), before upgrade it was 2.5 KB. Obviously utf font is embedded into the pdf.

#10 Updated by David Strejc over 14 years ago

I can confirm that this patch works for Czech language.

#11 Updated by Sergej Jegorov over 14 years ago

I confirm, that patch works for Lithuanian language.

#12 Updated by Azamat Hackimov over 14 years ago

Works fine for Russian. Tested for gannt and task. Is possible reduse filesize of generated PDF?

#13 Updated by Jean-Philippe Lang over 14 years ago

French works with "vera" font.
A error is raised for japanese, traditional chinese and simplified chinese.

#14 Updated by Jan Topiński over 14 years ago

I tried to fix Japanese and Chinese but I can't. I'm afraid that it's time to switch redmine to something like prawnto. I can volunteer to do it if you Jean think this is the right path.

#15 Updated by Jan Topiński over 14 years ago

This two pdf files are generated with prawnto version of a issues index view. French-Polish praw-pl-fr.pdf seem ok Japanese is ok but latin fonts look ugly attachment:/praw-jp.pdf.

#16 Updated by Jan Topiński over 14 years ago

I'm sorry Japanese file was too big and did not made to the page so I attach a screen-shot of it praw-jp.png.

#17 Updated by Jean-Philippe Lang over 14 years ago

Jan, these pdf generated with prawnto look good (except the fact that praw-pl-fr.pdf contains the html layout).
If prawnto offers the required functionalities, switching would be a solution. Could you post the patch you used to generate these pdf ?

#18 Updated by Jean-Philippe Lang over 14 years ago

I've made a few tests with prawn. It's much more easy to use than rfpdf but it's much slower. The generation of a list of 100 issues takes about 10s on my box (<1s with rfpdf). I'm afraid that it makes it unusable.

#19 Updated by Jean-Philippe Lang over 14 years ago

Looks like it's faster when using ttf fonts:
  • dejavusans: 3s
  • comicsans: 1.75s

#20 Updated by Eric Davis over 14 years ago

rfpdf is causing my mongrels to die and timeout quite frequently now. It's happening so much that I'm turning off all PDF export on my installation. I'm interested in seeing how prawn performs against rfpdf with my issue data.

#21 Updated by Jan Topiński over 14 years ago

Requested patch is here prawn.patch (for testing only).
To use it one needs to install prawnto:
  1. install prawn:
    gem install prawn
  2. install prawnto:
    script/plugin install git://github.com/thorny-sun/prawnto.git

Jean: the only problem apart of performance can be with gantt, there are some issues with prawn and png in tables. I will try to make the gantt pdf and we will see.

#22 Updated by Heejong Lee over 14 years ago

Your patch causes permission denied error.

#26 Updated by Alexey Kornilov about 14 years ago

We have hust upgraded to 0.8.4 release and the exported pdfs are now broken again. We are using Russian for our projects.
Formerly we have successefully used the 61.patch by Jan Topiński for version 0.8. Now it seems that the architecture has been changed, so the patch does not help anymore.

The screenshot is attached

#27 Updated by Maxim Krušina almost 14 years ago

  • Priority changed from Normal to High

Hi there, any rpogress with ths issue?
Should I ask our guys to look on this issue?

#28 Updated by Gyoung-Yoon Noh almost 14 years ago

Exporting to PDF breaks Korean characters in trunk. I fixed this, but I am not sure that it is right solution. This fix is dependent on UnDotum font, which is included in unfonts package licensed by GPL.

Sorry, it does not depend on unfonts package. It will work on any UHC-inclusive font package.

#30 Updated by Stanislav German-Evtushenko almost 14 years ago

I have tried to change output fonts from Helvetica to FreeSans (Helvetica doesn't support Cyrillic). Font have been changed in output PDF but Cyrillic text is still unreadable.

#31 Updated by Szymon Połom almost 14 years ago

Can confirm this issue.

My last name is Połom but it gets exported as PoÅ‚om to a PDF.

#32 Updated by Konstantin Ershov almost 14 years ago

Also confirm that in Redmine 0.8.4 I have broken PDFs with cyrillic characters.

I have "Задача" instead of "Задача".

#33 Updated by Konstantin Ershov almost 14 years ago

Solved for Redmine 0.8.4.

Standart rfpdf was replaced with rfpdf from http://github.com/edwinmoss/rfpdf/zipball/master and then we made some changes mentioned above with lib/redmine/export/pdf.rb.

Patch is atached.

PS Exported PDF's include embedded fonts.

I and my friend have tested prawn.patch (http://www.redmine.org/attachments/1185/prawn.patch) (thanks to Jan Topiński and Heejong Lee). Cyrillic and Japanese symbols are displayed correctly. So prawn might be right solution.

Quote: Jan Topiński
I think I've fixed that one. See bulg.pdf.

To fix it one needs to

1. Update rfpdf to the newest version:
script/plugin install git://github.com/edwinmoss/rfpdf.git --force
2. Apply attached patch:
patch -p0 < 61.patch

Pdf export worked fine for me (Polish) and for Bulgarian.
Q: from above in step 2 . Apply attached patch how to operate it , patch -p0 < 61.patch, is it command or what?

#39 Updated by Anonymous over 13 years ago

I've tested similar solution, but it does not work with Chinese and Japanese fonts.

Redmine ver.0.8.4 has code in app/controllers/issues_controller.rb line 70 different from this patch >> http://www.redmine.org/attachments/1181/prawn.patch
in patch 70 : format.pdf { send_data(render(:template => 'issues/index.rfpdf', :layout => false), :type => 'application/pdf', :filename => 'export.pdf') }
in Redmine v0.8.4 70 : format.pdf { send_data(issues_to_pdf(@issues, @project), :type => 'application/pdf', :filename => 'export.pdf') }

So, i change patch above to attached patch in order to able to apply with Redmine v0.8.4
but it also doesn't work .

+1 for this issue. Export PDF is broken for Russian language.

Way to reproduce:
Select "My account" on the top of this page and change language to Russian or Bulgarian.
Then just export any issue from this site to PDF.

Instructions for latest RFPDF (TCPDF):

The 61.patch sometimnes doesn't work correctly with redmine 0.8.7 stable.

Users can manually change this file: redmine-0.8.7/lib/redmine/export/pdf.rb and remove/change affested lines (see: http://www.redmine.org/attachments/1150/61.patch).

Propably You need also change this file: vendor/plugins/rfpdf/lib/rfpdf/template_handler/compile_support.rb and disable below lines:

  1. extend ActiveSupport::Memoizable
  2. memoize :ie_request?
  3. memoize :ssl_request?

#43 Updated by K S about 13 years ago

For polish coding you must change a redmine/lang/pl - pdf and cvs section to UTF-8 characters (not iso, if you use FreeSans font!).

#44 Updated by Jeffrey Jones about 13 years ago

I am late to the party on this one.

Does anyone have a list of steps that need to be followed to enable Japanese PDF output on 0.8.7-stable? I am looking through the history and it looks like I have to

1. update rfpdf
2. apply the 61.patch
3. Do the steps KS listed in previous post.

Is this correct?

#45 Updated by Jeffrey Jones about 13 years ago

Ok, so this is how I have managed to get it (half) working on 0.9.1

  1. Update RFPDF with
    script/plugin install git://github.com/edwinmoss/rfpdf.git --force
    
  2. Update redmine-0.8.7/lib/redmine/export/pdf.rb so that it matches http://www.redmine.org/attachments/1150/61.patch (NOTE: The patch changes some view files but these have been removed and all the AliasNBPages changes are also in the pdf.rb file)
  3. Edit vendor/plugins/rfpdf/lib/rfpdf/template_handler/compile_support.rb and comment out the following lines:
    extend ActiveSupport::Memoizable
    memoize :ie_request?
    memoize :ssl_request?
    

Doing this means that I can output PDF files. HOWEVER these files can only display Hiragana and Katakana and cannot display Kanji, so practically useless at the moment.

Hi, PDF export has still broken some chars in czech language. I have latest RFPDF plugin, Redmine 0.9.3 and all texts are stored in UTF-8. Doesn't matter if you apply #61. How to make it works? Thanks.

#50 Updated by Vladimir Kovacik almost 13 years ago

Besides updating the rfpdf plugin and applying the patch you need to make sure your selected language locale uses "general_pdf_encoding: UTF-8".
Despite I'm Slovak I prefer english language for my user in Redmine. However english locale contained "general_pdf_encoding: ISO-8859-1" which obviously cause problem in case. I changed it to UTF-8 and now it works smoothly...

I've enahnced Aleksander Palyan's patch for automatic enable/disable CJK helper modules by value of general_pdf_encoding.
(because CJK helper modules will troubles when UTF-8/Unicode mode.)
but it need to change font manually.

for UTF-8/Unicode font job, follow this guide.

#58 Updated by Leo Hourvitz over 12 years ago

I tried Sin-young's enhanced patch against redmine-1.0.1 on Mac OS X 10.6. I did change the pdf encoding in the locale to utf-8 but had no other problems in English or Japanese, excepting of course the elephant in the room: because of the font problem Jeffrey mentioned, you only get hiragana and katakana in the output, so it's structurally complete and yet useless for real work!

I tried to convert one of my .ttf Japanese fonts with the ttf2utm utility but I couldn't get it to output a valid file.

It's correct patched source.

I tried it in Japanese locale, so The same error occurred in production mode.
but, in development mode (RAILS_ENV = 'development'), I don't detect error. why?

I tried to debug. I found...

I changed by way of experiment as follows. so, it doesn't detect error...

#      class IFPDF < (l(:general_pdf_encoding).upcase == 'UTF-8' ? TCPDF : FPDF )
      class IFPDF < (l(:general_pdf_encoding).upcase != 'UTF-8' ? TCPDF : FPDF )

#        alias alias_nb_pages AliasNbPages if l(:general_pdf_encoding).upcase != 'UTF-8'
        alias alias_nb_pages AliasNbPages if l(:general_pdf_encoding).upcase == 'UTF-8'

Check your database encoding is UTF-8.
MySQL default encoding is Latin-1(ISO-8859-1).

In English locale, Redmine trunk uses embedded FreeSans font.
FreeSans does not have Chinese HANJI (漢字).
In Simplified and Traditional Chinese locale, Redmine trunk uses non embedded font.

The database should be in UTF-8, as it could display Chinese on the Redmine web interface.

Dear Toshi,

Thank you very much! Your advices are very helpful!
Now I managed to Print PDF in with Chinese correctly.

One more think to add, is there any way I could change to font type? It is because the Chinese PDF does not look good, although the display is correct. Is there any way I could modify the RFPDF so to change the font name?

Font names are hard-coded at source:trunk/vendor/plugins/rfpdf/lib/fpdf/chinese.rb#L80 .

pdf_encoding.patch and locales_encoding.patch switch to use to "general_pdf_encoding" from "current_language".

If you are an English locale(use en.yml), set "general_pdf_encoding: gb18030" in en.yml.
So you can use English interface and generate Chinese PDF.

I found 0x5c char handling bug, for Japanese and Chinese PDF. (Korean PDF don't have 0x5c char handling problem.)

I had done the 0x5c escape processing before using japanese.rb (chinese.rb).
Therefore, the mistake occurred in byte calculation because the number of 0x5c escape characters increased.

sample : This problem occurs by the character string that contains 0x5c.
