A whole novel in French

The same layout on a French text: a hundred and forty-five pages drawing the accented alphabet, so the font kept inside the file carries every shape a wider alphabet needs.

//! Lays a whole French novel out and writes it as one PDF.
//!
//! The twin of `write_book`, on a text that draws the accented letters as well
//! as the plain ones. It shows what a wider alphabet costs: more outlines to
//! carry, and metrics still stated only for the glyphs the book draws.
//!
//! Usage: `cargo run --example write_french_book -- tmp/french_book.pdf
//! [font.ttf]`
