What is this?

This is a map from the HTML spec of C1 ASCII/Unicode control characters (which are disallowed by HTML) to the characters those code points would have in Windows 1252. For example, U+0080 (Padding Character) maps to €, because that’s used for 0x80 in Windows 1252.

When should I use this?

Probably never, unless you’re dealing with parsing HTML or similar XML-like things, or in a place where Unicode is not the primary encoding (it is in most places).
