Most mobile browsers can't the, last time I checked. Although, it's easy enough to read PDF with so many options on Android, but opening another viewer and then zooming, scrolling is just painful. PDF might guarantee the formatting but I think it should only matter when it comes to printing. Besides that, fixed size containers and fluid grids give plenty of flexibility with web documents. So in case, the author intends to have fixed formatting, I think it's achievable with HTML and CSS.
