ASCII 125 — }

The right curly brace closes code blocks, object literals, CSS declaration blocks, and other structures opened by the left curly brace. Mismatched braces are a frequent source of syntax errors, and virtually all modern editors provide brace matching, rainbow coloring, and auto-closing to prevent them. In JavaScript template literals, '}' closes embedded '${expression}' interpolations. In regular expressions, '}' closes quantifier ranges like '{2,5}'. The right brace pairs with the left to define scope and grouping in dozens of programming languages across all paradigms.

Punctuation marks serve as the structural scaffolding of written language, delineating sentences, clauses, and phrases while conveying emphasis and grouping. In programming, these same characters gain powerful additional roles as operators, statement terminators, delimiters, and syntactic markers that compilers and interpreters rely upon. This dual significance in both natural language and code syntax means punctuation characters carry outsized functional importance relative to their small count in the ASCII character set.

In the ASCII encoding table, Right Curly Brace is assigned code point 125 in decimal (0x7D hexadecimal, 175 octal, 01111101 binary). The 7-bit ASCII standard, first published in 1963 by the American Standards Association, defines exactly 128 characters that remain the foundation of text encoding systems worldwide. UTF-8, the dominant encoding on the modern web, is fully backward compatible with ASCII — every ASCII character is encoded as the identical single byte in UTF-8, guaranteeing that Right Curly Brace works reliably across all operating systems, programming languages, and internet protocols.
