Reads the PDF catalog's /Lang entry — the document's declared natural language as a BCP-47 tag (e.g. "en", "en-US"). Wraps FPDFCatalog_GetLanguage (PDFium chromium/7857+), the reader counterpart to pdf_doc_set_language().

Usage

pdf_doc_language(doc, password = NULL)

Arguments

doc

A pdfium_doc from pdf_doc_open(), or a character path.

password

Optional password for encrypted PDFs when doc is a path. Ignored when doc is already an open pdfium_doc.

Value

Character scalar — the BCP-47 language tag, or "" when the document declares no /Lang.
