Dave Opstad is one of the co-founders of Unicode 1.0[1][2][3], together with Huan-mei Liao, Nelson Ng and Lee Collins). He worked on Apple's TrueType font specifications and holds several patents.[4][5]
Early life and education[edit]
Opstad has a Bachelor of Arts in Chinese and a Master of Library Science from University of California, Los Angeles.
Career[edit]
He worked for IBM, Xerox, Apple. All in all, he ended up with over 50 years of professional experience after he retired from Monotype in 2020.
During his time at Apple, he was responsible for AAT, where he designed (for example) the 'Zapf'[6] table, named after the type designer Hermann Zapf. In the 1990s, Dave Opstad (together with people like Tom Rickner) was initially involved in the development of TrueType GX[7]. This font technology was forraus of its time. But there was a lack of support[8]. At that time software producers like Microsoft or Adobe did not implement the necessary support for this new technology, why it never became a new standard. GX was certainly the basis of variable fonts, (also known as OpenType font variations). Most of the time he worked behind the scenes, yet he was often asked for advice.[9][10]
His fundamental work on Unicode and TrueType enabled easy exchange of messages between different devices and operating systems (without TOFU (also knows as .notdef)) – all over the world.

In 1978, the initial proposal for a set of "Universal Signs" was made by Bob Belleville at Xerox PARC. Many persons contributed ideas to the development of a new encoding design. Beginning in 1980, these efforts evolved into the Xerox Character Code Standard (XCCS) by the present author, a multilingual encoding which has been maintained by Xerox as an internal corporate standard since 1982, through the efforts of Ed Smura, Ron Pellar, and others.
Unknown parameter
Unicode arose as the result of eight years of working experience with XCCS. Its fundamental differences from XCCS were proposed by Peter Fenwick and Dave Opstad (pure 16-bit codes), and by Lee Collins (ideographic character unification). Unicode retains the many features of XCCS whose utility have been proved over the years in an international line of communication multilingual system products.|url-status=ignored (help) - ↑ "Chronology". www.unicode.org.

I got the impression that developers like Aldus, Adobe, and Quark are reluctant to implement portions of QuickDrawGX because there is no equivalent technology for Windows.
