What is this?

This is a list of certain named character references, that due to legacy
reasons, don’t need a trailing semicolon in HTML.
For example, © is perfectly fine for ©!

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].
