History & usage: The Z notation left binding bracket is a symbol in the Miscellaneous Mathematical Symbols-B block. It carries the codepoint U+2989. In use, it helps mark the start of a binding group. The bracket also functions to delimiter groups, parameters, or quoted text in writing and code. Users rely on it to show where a set or sequence begins and where it ends, especially when brackets nest. In formal writing, it works with other brackets to keep structure clear. The same idea appears in programming and specification work, where precise grouping matters. This left binding bracket stays recognizable at a glance and reduces ambiguity in dense notation. It is used alongside other delimiters to separate elements and to frame quoted material. When authors present parameters or arguments, the bracket signals the scope of those items. The symbol is usually paired with a matching right bracket to close the group. Over time, readers and writers learned its role in organizing complex expressions. Its simple function — delimiting and binding — keeps technical text readable. Strong use of the symbol supports clarity in formal documents and code alike.

Copy and input: the quickest method is to copy the character here. You can also insert it by its codepoint U+2989 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.
