📖Ghost Characters in JIS X 0208 Encoding From 1978
Mistakes from the '70s are now Unicode standards
TL;DR
In 1978, Japan's Ministry of Economy, Trade and Industry established JIS X 0208 encoding with several ghost characters. These mysterious symbols were later found to be cataloging errors or misreadings from obscure documents.
In 1978, Japan introduced the JIS X 0208 encoding standard, which included a set of ghost characters — symbols without clear origins or meanings. An investigation in 1997 revealed these characters were often cataloging mistakes or misreadings from obscure documents like 'Overview of National Administrative Districts'. One character, 彁, had no historical precedent and was likely a misreading of another symbol. These errors made their way into Unicode standards, affecting every computer system today.
Key Points
JIS X 0208 established in 1978 included several ghost characters (幽霊文字).
Investigation in 1997 found origins in obscure documents like 'Overview of National Administrative Districts'.
The character 妛 was a cataloging error while trying to record '山 over 女'.
Only one ghost character, 彁, had no clear source or historical precedent.
Following JIS adoption, these characters made their way into Unicode standards.
Why It Matters
If you're working with Unicode in any capacity, the history of ghost characters is crucial. These mistakes from 1978 are now part of every computer system globally. The character 彁, for example, was likely a misreading and has no historical precedent.
