As an ex CNC router operator & engraver in the signage industry I used all types of fonts. Anything that wasn't vector based had to be converted and/or scanned and vectorized. And yes, bit size, offset (for routing, not engraving), nesting (for routing), path & kerning are all important aspects that have to be considered when setting up a job. When I started in 1990 all of that was a lot harder because we were using DOS on a Commodore but those things can be easily manipulated using today's software. And yes, to a comment below about kerning. From a signage perspective that is definitely an engraving font and it has serious kerning issues. Fortunately that can be adjusted with signage software.
