OpenType

OpenType is a joint venture between Adobe and Microsoft. It is based on Unicode (a platform-independent encoding that covers the world's languages). There are several attractive concepts behind OpenType; one is that each OpenType font can contain over 65,000 different glyphs, these can include small caps, old style figures, swash forms and foreign language scripts. There is also the ability to add 'intelligence' to the fonts through the addition of OpenType features. Beyond all that, the same font file works on Macintosh and Windows making incompatibility a thing of the past. OpenType is supported natively on the latest operating systems including Mac OS X, Windows Vista, XP and 2000. If you intend to use OpenType fonts form Jeremy Tankard Typography on Mac OS 9.2 and below or Windows 98/NT/ME and below you will need to install the free ATM Light application from Adobe.
