Install PDFium's default system-font-info provider

Wraps FPDF_SetSystemFontInfo(FPDF_GetDefaultSystemFontInfo()). Tells PDFium to use the platform's default callback table for resolving font requests against installed system fonts. Without this, PDFium falls back to its built-in (static) substitution table only — which is fine for most documents but misses platform-installed typefaces.

Usage

pdf_system_fonts_install_default()

Value

Invisibly returns TRUE if the provider was installed, FALSE if the platform has no default provider (e.g. stripped-down builds).

Details

Idempotent across calls; the provider persists for the package's lifetime (PDFium retains the pointer; we don't call FPDF_FreeDefaultSystemFontInfo because the provider is library-global).

Custom providers (R-side callbacks for font enumeration) are deferred to a later release — they require marshalling FPDF_SYSFONTINFO's callback table into R closures, which is non-trivial.
