85. Seven bit ASCII caused the ascendance of computer architecture based on8 16 32 64

86. If ASCII had been successfully completed as a six bit set, 36 bit architecture would have survived.The first microprocessors would have been 12 bit machines, not 8.

87. Europe would have moved immediately to 12 bit character sets, just as Asia had to adopt double byte character sets.By avoiding character substitution, most internationalization problems would have been avoided from the beginning.

88. Ultimately, the world could have adopted an 18 bit universal character set.72 bit cpus would become the standard.

89. Standards need to be reevaluated regularly, and eventually replaced.That is how progress works.
