What Is an HTML Encoder?
An HTML Encoder converts characters that have special meaning in HTML into safe entity references. This allows HTML code, symbols, and reserved characters to be shown as text instead of being interpreted as part of a web page.
For example, the less-than symbol < normally begins an HTML tag. Encoding it as < tells a browser to display the character instead of treating it as markup.
Why Is HTML Encoding Important?
HTML encoding is useful when displaying source code, special characters, user-provided text, examples, documentation, templates, and other content where reserved HTML characters should remain visible.
Characters such as ampersands, less-than signs, and greater-than signs can affect the structure of HTML. Encoding these characters allows them to appear as normal visible content.
Named vs Numeric HTML Entities
Named entities use readable references such as < and &. Decimal numeric entities use character numbers such as <, while hexadecimal entities use values such as <.
What Is Double Encoding?
Double encoding happens when an already encoded entity is encoded again. For example, < could become &lt;. The prevent double encoding option helps preserve existing entity references.
