Anyone know of where to get a font to print checks using magnetic ink?

Example: at the bottom of a check, there's a series of numbers; the first portion refers to the bank routing number, the last refers to the account number along with actual check number. The numbers at the bottom of a check are printed in a special computerized font, using a couple of characters I do not recognize.

If anyone out there has information they could share, I'd greatly appreciate it!

Sincerely,
