Set the document language
Setting the document language in a PDF enables some screen readers to switch to the appropriate language. You can set the document language for an entire document with Acrobat Professional, Acrobat 3D, or Acrobat Standard. You can set the document language for specific portions of a multilanguage document with Acrobat Professional or Acrobat 3D.
- To set the language for an entire document, choose File > Properties, and select a language from the Language menu in the Reading Options area of the Advanced tab.
- To set the language for an entire document to a language not in the Language menu, choose File > Properties, and enter the ISO 639 code for the language in the Language field in the Reading Options area of the Advanced tab. For more information, see the ISO Language Codes on http://www.loc.gov/standards.
