## What is this?

This is a map of named character references in HTML 4 to the characters they
represent.

## When should I use this?

Maybe when you’re writing an HTML parser or minifier, but otherwise probably
never!
Even then, it might be better to use [`parse-entities`][parse-entities] or
[`stringify-entities`][stringify-entities].
