PDFium's default charset → TTF substitution map

Wraps FPDF_GetDefaultTTFMapCount + FPDF_GetDefaultTTFMapEntry. Returns the static "PDF charset code → TrueType font name" substitution table PDFium ships with the build. When a PDF references a font by charset code only (e.g. /Encoding /WinAnsi with no /BaseFont resolution), PDFium consults this table to decide which TTF to fall back to.

Usage

pdf_system_fonts_default_ttf_map()

Value

A tibble with columns charset (integer code) and fontname (character).

Details

Useful for auditing why a particular missing-glyph PDF rendered with a substitute font, and for confirming which charsets PDFium can serve without an explicit pdf_font_load().

See also

pdf_system_fonts_install_default() to install the platform's default sys-font-info provider so the substitution actually fires.
