What this tool does
By default, HTML Entity Encoder only processes special characters common in HTML text and attributes, and will not meaninglessly convert all Chinese characters into entities. Optional mode encodes non-ASCII characters into numeric entities by Unicode Code Point.
- The default encoding is the ampersand, left and right angle brackets, double quotes, and single quotes.
- The optional "Encode all non-ASCII" will correctly handle supplementary flat characters such as emoji.
- The tool only converts text and does not parse or execute user-supplied HTML.
