How does unicode-trie work?

[lancejpollard]

From the description I am imagining it loads the huge text file of descriptions of the unicode characters, their categories, and other properties. Is that what this does? If so, I don't see the data anywhere, how should it be used? Thank you for the help.

I imagine something like this. This repo is really interesting, if you did get the answer to the question please let me know. Thank you.
