uu is a command line program for inspecting Unicode text.
You can install uu via Homebrew.
brew install jake-low/tools/uu
Alternately, if you have a Rust toolchain installed you can download the source code for a release and build it with cargo build.
uu inspect will read from STDIN and print a line for each code point it finds, with details about that code point.
