History & usage: LEFT CURLY BRACKET UPPER HOOK U+23A7 is a punctuation symbol used in writing and computing. It belongs to the Miscellaneous Technical block. In many fonts, it shows as a curved left brace with an upper hook. The symbol helps to mark groups and parameters. It also helps to indicate quoted text in some code samples and in technical documents. Its style is distinct from common braces, so it rarely replaces standard braces in everyday writing. The primary use is grouping or delimiting parts of a sentence, data, or code. It guides readers to see where a group starts. It can stand in for other brackets when space or font choice matters. In coding, it may appear in contexts that require a visual cue for a parameter or a nested section. The character is part of a broader family of delimiters. It shares space with other brackets used for structure, quotes, and lists. Users rely on it for clarity and organization in technical material.
Copy and input: the quickest method is to copy the character here. You can also insert it by its codepoint U+23A7 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.
