Implement nonlingustic content language code |
| Request Submitted By | PDF/UA |
| Executive Summary | Specify language codes for content that does not use a natural language. |
| Rationale | PDF content does not have to use a natural (human) language. That content may nonetheless be made up of Unicode characters. Without correct language coding, adaptive technology might make a guess, usually an incorrect one, as to the language of the content and read it with nonsensical speech or Braille. BCP 47 provides language code zxx for such content. |
| Use Case(s) |
Non-linguistic content. |
| Details of Requested Change |
Add a new paragraph at the end of 14.9.2.2 as follows: Non-linguistic content should be marked with language code "zxx" (See ISO 639-2). |
