Font for proofreading

For those of you who find changing the font of a document makes it easier to spot errors - here's a font designed specifically for proofreading. http://www.pgdp.net/c/faq/font_sample.php?compare=Arial

I get the impression it's mostly designed for catching OCR errors (e.g. "cl" -> "d") but might still be worth a look.

Thanks for the information
