- The Chinese script is much older, it is some 8000 years old. This makes the Chinese script some 3500 years older that previously thought.
- Redhat made available the "Liberarion fonts", they are fonts that allow for the replacement of the proprietary Microsoft fonts. This is one of the impediments of adopting Linux. It is also one of the more visual aspects where Microsoft shows not to care about interoperability.
The SignWriting script is young, it represents a revolution in the signing world and it has to be adopted by many signing communities. It is different from other written representations of signing languages because it is actually used for day to day use. As a script, it is different from Chinese because it represent movements like the Latin script represents sounds while a Chinese character represents in essence a concept. For this reason the SignWriting characters will mean different things in different sign languages.
The Liberation fonts make it possible to replace the Microsoft fonts without a need for reformatting the text. When you analyse this, it means that Unicode characters are now available in two interchangeable sets of fonts.
SignWriting does not have Unicode characters and it does not have fonts. The symbols that it uses are complete for most sign languages and some missing characters for the Ethiopian Sign Language are being added at the moment.
One really powerful argument why SignWriting is so important is because it helps deaf people to learn a written language that is foreign to them. English is in essence foreign to a person who grew up with American Sign Language; the written English language is not connected to the every day language of the student. When you learn a second language, you learn the shared concepts quickly. Now in order to know what these shared concepts are, you use a dictionary. Without a dictionary, without a written representation of the primary language, it is extremely hard to learn. It requires a really well trained memory.
It is exactly because of deaf people having to live in a world based on sounds that the bridge that the written word is so important. There is anecdotal evidence that kids who learned to write their sign language are better able to learn the written language of the spoken language that surrounds them.
It is for all these reasons that SignWriting emancipate the deaf. It will emancipate them because as a group they will become better able to communicate in their own world. A world that is both signing and speaking.
