PDF Accesibles en dos idiomas? Se puede hacer?

[Sandra296876340igt]

Hola buenos días, a ver si algún experto en materia me puede ayudar.

Tengo un libro de formación (idiomas) que interconecta dos idiomas, Castellano y Urdú. Sobre el que tengo que aplicar criterios de accesibilidad, se podría hacer que el PDF interprete cada uno de los idiomas de manera correcta? Ahora mismo al leer dos lenguas distintas, con sistemas de lectura distinta, no lo hace correctamente...

¿Alguien me puede decir si es posible?
Muchas gracias.

Yes, this can be done in an accessible PDF.

Requires 3 things:

1. Choose one language and set it as the global (or primary) language of the PDF.  That's set in File / Document Properties / Advanced tab. Toward the bottom, set the main language from the Reading Options section. Example, by setting the global language to Spanish will apply the Spanish language attribute to the entire PDF.
   Document Properties sets the file's dominant language.
   
   
2. Set the secondary language for the text in Urdu. This is done on each tag that is in the secondary language. Select the tag / Right-click / Properties, and choose the language from the drop-down menu. If the language isn't in the menu, type in the language code listed here at ISO 639-2: https://www.loc.gov/standards/iso639-2/php/code_list.php   Urdu = urd, not Urdu.
   Language attribute for Urdu.
   
   
   If only 1-2 words in a paragraph are in the secondary language, then create a <Span> tag around those words and put the ISO 639 language code on the <Span> tag.
3. Use either a language-specific screen reader, or add a language pack to the screen reader for the secondary language. Check the screen reader manufacturer's website for details.

Urdu is a right-to-left language similar to Arabic. From experience with Arabic, Accessibility doesn't work well in PDF and mostly quite few steps must be done manually
