    Accessibility PDF in Tamil - The Worst Nightmare

    sebdea Level 1

      Hi there,


      Here are tech details:


      MAC OS X 10.9.3, InDesign CC, MS Word file provided in Tamil using Arial Unicode.


      I imported the text into InDesign (since I received a template in English for that document). I formatted document using the template styles. Exported as PDF from InDesign. Went to Adobe Acrobat and ran Tools - Accessibility - Full Check. It returned 6 errors divided as follows: Document - 4 and Page content - 2.


      Document: Logical reading orders - left as is; Primary Language - I added TAM for Tamil - Passed; Title - Fixed - Passed; Color Contrast - left as is.


      Page content: Tab order - fixed -Passed; Character Encoding - Failed (20 Words). In the screenshot you will see the character that returns that error.

      As you can see it's repeating all over the document.


      According to Help file of Adobe it looks like a font issue. Since Arial Unicode is installed on MAC I looked further for other fonts. That way I understand that it is wide used InaiMathi.ttf


      I changed entire document font to Inai Mathi. I created the PDF, I checked it for full accessibility. There was no error regarding Character Encoding - Passed. Yet, the client returned the document to me saying that there was an error regarding the font.








      Now I am stuck. As I read on various Forums, including on this one, the only thing left for me to do is to change the font. To what? At a point I found 120 fonts for Tamil. I tried 12 of them. Most of them are returning same 20 Character Coding error and I even found one that returned 40 Character coding errors.


      As a indirect question to my issue, is there a chance to select what font to be used when adding ALT TEXT to Images in InDesign?

      Any valuable input will be appreciated. I do have a Windows partition on my MAC in case that the only solution is to format the document under Windows.


      Thank you for your time and help.


      Sincerely yours,

          Hi Sebastian,


          I have no experience with Mac, InDesign, or the Tamil language, but I won't let that stop me from taking a stab in the dark! Regarding the PDF that passed for you but failed for the client - was the font embedded? I am not really sure if that would make a difference but it is something I would check. You can embed fonts in Acrobat Pro using Preflight - at least on a PC - unless the font forbids embedding. I would think if the font is embedded it should behave the same on any machine, but again, not completely sure.

            Thank you for your reply. The fonts, no matter what fonts I am using, are embedded in PDF. The issue is not that is showing differently on a computer versus another. It is simply something related to font coding. As I read on a forum, it looks like Arial Unicode is showing Old Tamil letter/signs.


            Best regards,

              To fix the issue with the vowel sounds you just have to select the text and enable the World Ready Para Composer option in the Paragraph panel. Hope this helps!
