HTML Encode
Convert any string into HTML-safe entities. The 5 reserved characters (&, <, >, ", ') are always escaped as named entities; non-ASCII characters can optionally be encoded as numeric entities (&#NNN;) so the result is safe to embed in 7-bit ASCII HTML. Runs entirely in your browser — your text is never uploaded.
