ascii is small CLI tool to display information on the ASCII characters as a table.
It can be installed from PyPi using pip, pipx or your favourite tool of choice.
pip install rich-ascii
If called with no options it will display the decimal value, hexadecimal value and name in 2 sets of columns (0-127 in the first and 128-255 in the second).

It also supports highlighting a specific item by passing the number to highlight either as a decimal of a hexadecimal number.
You can also control the style of the table with the following options
--style = The style of the text
--title-style = The style of the table title
--header-style = The style of the table header
--highlight-style = The style of the highlighted row
See the Rich dcoumentation for details on how to specify a style.
Uses the rich library for the fancy table formattting.
The aliases are taken from the NameAliases.txt file provided as part of the Unicode UCD

The output does look better than it appears on the web. Github mangles it by changing the line height from 1 and PyPi mangles it even worse.
