Right Square Bracket ]

The Right Square Bracket character (]) is a standard HTML entity defined in the HTML specification. In HTML source code, it can be written using the named entity reference ], the decimal numeric character reference ], or the hexadecimal numeric reference ]. The character is assigned Unicode code point U+005D in the Universal Character Set.

The right square bracket closes array notation, markdown links, character classes in regular expressions, and mathematical interval notation. It pairs with the left square bracket and rarely needs entity encoding in standard HTML, but may be needed in specific parsing contexts.

Technical character entities represent brackets, delimiters, and punctuation marks that frequently require escaping in HTML source code and programming contexts. Characters like curly braces, square brackets, pipes, and backslashes often carry special meaning in templating engines, regular expressions, or markup parsers, making their explicit HTML entity encoding important for preventing unintended interpretation by the browser or build tools.

When deciding how to encode the Right Square Bracket character in your HTML documents, the named entity ] is generally the most readable choice for developers reviewing or maintaining source code. The decimal form ] and hexadecimal form ] are equally valid alternatives that work in contexts where named entities may not be supported, or when generating HTML output programmatically from server-side code. All three representations produce identical visual output in every modern web browser.

Use the right square bracket entity alongside [ when displaying content that might be processed by markdown parsers, regular expression engines, or other bracket-sensitive systems. It ensures the literal character is displayed rather than interpreted.
