Notes
- Only five characters must be escaped in HTML content: & < > " and ' — everything else is optional when the page is UTF-8.
- Numeric entities (&#8212;) work for every Unicode character; named entities exist only for a curated list.
- Runs 100% in your browser — nothing you paste leaves your device.
