SetDocumentLanguage

Document properties, Accessibility

Description

Sets the document's natural language in the PDF Catalog (/Lang entry). The language declaration is used by screen readers and other assistive technology to apply correct pronunciation and text-to-speech rules.

This function writes the Catalog /Lang key directly. When using PDF/UA mode, the language should instead be supplied via the SetPDFUAMode Language parameter, which calls this function internally.
