/* Adapted from OCR-B font version 0.2 Matthew Skala
* https://tsukurimashou.osdn.jp/ocr.php.en
*
* Copyright Matthew Skala (2011); based on code by Norbert Schwarz (1986, 2011)
*
* "The version in this package descends from a set of Metafont
* definitions by Norbert Schwarz of Ruhr-Universitaet Bochum,
* bearing dates ranging from 1986 to 2010. He originally
* distributed it under a "non-commercial use only"
* restriction but has since released it for unrestricted use
* and distribution. See the README file for more details."
*
* The README states (http://mirrors.ctan.org/fonts/ocr-b.zip)
*
* "As far as the digitization in METAFONT input which I have
* developed, you may freely use, modify, and/or distribute any of
* these files or the resulting fonts, without limitation. A previous
* release of ocr-b only granted rights for non-commercial use; that
* restriction is now lifted."
*
* Used OCRB.otf with FontForge to create OCRB-18.bdf (normal) and OCRB-16.bdf (small) and then touched up using gbdfed
* Note there's no bold version of OCR-B.
