Inputting and outputting character text by machine with Chinese characters presents a totally different set of challenges than is faced by writers in languages that use phonetic scripts, whether the technology used is woodblock printing, movable type, keyboards or computers. One solution to these problems would have been to convert Chinese to a phonetic script, and part of what this book covers is the waves of advocacy for that idea and the different systems of Romanization that have been tried, as well as efforts that have been made to develop a phonetic script designed specifically for Chinese. But there were many reasons not to go phonetic, including the ability of Chinese characters to be understood across Chinese dialects that are otherwise not mutually comprehensible, the unique nuanced expressiveness of Chinese characters, the long history of culture and empire associated with the Chinese writing system, and of course, not the least reason, national pride.
But then if you are sticking with traditional characters, how do you input and output them with machines? Outputting was a challenge in a world where you needed a separate lead slug to represent each of the thousands of characters. This problem was mitigated but not solved by the orthographic reform under Mao, but now with modern computer screens and inkjet and laser printers, outputting has become trivial. Inputting remains an issue. Early attempts at typewriters used limited character sets and managed the problem by constructing the characters from pieces, with many systems tried and then settling on one with tops, bottoms and middles that would be composited into whole characters. If you could manage to select a character representing an entire word with three keystrokes, it could in concept be more efficient than Roman alphabet keyboards, but in practice it is never as simple as that. Still, years of experimentation have produced systems that enable significant efficiencies, and computer algorithms for anticipating and suggesting the next word can help a lot.
The human part of the history presented in this book was interesting, but less compelling than the story of technological progress and the overcoming of political and social obstacles, but putting individual histories aside, there is something deeply human in the choice to retain the character writing system for its richness and cultural importance, rather than shedding it as soon as it became inconvenient to economic progress. Now with computers, the obstacles to using characters are greatly diminished so the choice doesn't feel self-defeating. And the world is a richer place by reason of having saved this system that provides an alternative method of expression that allows thoughts to be expressed in writing in ways that alphabetic systems sometimes cannot match.
