Open Type fonts
Scalable computer fonts conforming to the ISO open standard on typography and which can be used across computer platforms. Open Type fonts are now produced by virtually all type foundries and are available for a myriad of alphabets and scripts.
An ISO character-encoding standard for fonts and data storage that allows common mapping not just of the single-byte character sets found in Western alphabets but also of double-byte script systems such as Chinese, Japanese and Korean.
(Two definitions is a start. But, for what it’s worth, our book has about 100 such entries.)
