History & usage: The Right Square Bracket Extension, code point U+23A5, belongs to the Miscellaneous Technical block. This symbol is part of the set of brackets used in text and code. It serves to mark the end of a group or unit of text when other brackets are already in use. In practice, people may use it to close parameters in diagrams, scripts, or data formats, especially when standard brackets are used for other purposes. The usage note for this character is simple: brackets and quotes delimit groups, parameters, or quoted text in writing and code. This makes the symbol useful in technical writing and informal notation. As an extension, it helps avoid confusion when multiple bracket types appear in a single line. Writers and programmers adopt it to separate elements, set apart values, or indicate boundaries. The character is widely supported in fonts and input methods, but it remains less common than common braces or parentheses. It is part of the Unicode standard to provide alternative delimiters that are easy to recognize in arrays and lists.

Copy and input: the quickest method is to copy the character here. You can also insert it by its codepoint U+23A5 in many development tools or editors. Some operating systems provide a character viewer or input palette that lets you search by name or code and insert the glyph into documents.

Display and fallback: if you see an empty box (tofu) or a placeholder rectangle, the active font might not include this codepoint. Switching to a font with broader Unicode coverage or using a fallback font usually fixes the issue. On the web, ensure the page’s font stack includes a general‑purpose fallback.
