HTML Entity Encoder / Decoder

How it works

Encode escapes the five characters that are meaningful in HTML — & < > " ' — to & < > " ', so the text is safe to drop into an HTML document. Decode reverses those five named entities, and also understands numeric entities such as A (decimal) and A (hex) — both decode to A. A malformed entity with no trailing semicolon, like &amp, is left alone as ordinary text.
