One interesting thing is it's encoding system. Unlike Unicode that unified Chinese, Japanese and Korean characters, TRON had a different code points for characters that have the same root but are written differently in the different languages.

Unicode claim it's the same character and you need to use different fonts for different languages.

So TRON made it much easier to mix Japanese and Chinese, for example have a citation in Chinese in a book otherwise in Japanese.

It also had a lot more characters. Unicode dropped some of the older or rare characters, meaning some people can't write their last name with the correct character on a computer with Unicode. They have to use a similar but different character. With TRON, they could.

That said, this might be an example of why TRON didn't succeed (rather than this bullshit about the US government). They remade everything, which wasn't great for interoperability and compatibility with other systems.
