Description
Pandoc already supports the lang variable for setting the document language (following the BCP 47 standard). PDFs can include such a language definition as described in the
- Techniques for WCAG 2.0 (PDF16) and
- Techniques for WCAG 2.0 (PDF19) and
- PDF 1.7 Specification > Section 14.9.2.3 Language Specification Hierarchy.
One can set the PDF language parameter via the hyperref package with the option pdflang. The W3C page mentions that the PDF language definition has to use the ISO 639 language code but the hyperref documentation states support for RFC 3066 language codes. I don't know much about these standards but the pandoc language code looks quite similar so that we might be able to simply pass it to hyperref like this:
\hypersetup{
pdflang={$lang$},
}It also might be trivial to map between codes, should it be necessary.
