In the introduction to RTK3, Heisig states that originally "JIS-1" consisting of less than 3,000 kanji was installed as standard on computers, and a second list of around 4,000 kanji "JIS-2" was sold separately. Then on top of that, there was a "JIS supplement" consisting of an additional 5,801 kanji.
This means a total of around 12,800 kanji are available on computers at least when the introduction was written.
Here's my question: what exactly is the point of having 12,800 kanji on your computer? No human being could possibly remember that many. Why would someone need to use obscure kanji that their readers probably have never seen before? What are these additional vocabulary items anyway? And even if you know a select few readers out there may know these kanji, what's the point? Why not just write it phonetically?
Modern written Japanese does not require 12,800 kanji. I don't know, maybe before the post-war reforms it made more sense but why would anybody possibly need that many kanji on their laptop today?
I'd be curious to know if any of the 5,801 kanji from the JIS supplement are used often enough to justify having them on your PC.
