Description

The Unicode character U+23AA, known as the Curl Bracket Extension, is a typographical symbol that has a significant role in digital text. It is commonly used in computer programming, specifically within curly brackets to denote a block of code. In this context, the Curl Bracket Extension serves an important function by extending the width of one curly bracket while narrowing the other to improve visual alignment in certain coding layouts. This can enhance readability and comprehension for programmers working with languages such as C, C++, and JavaScript. While not widely used across all typographic styles and contexts, the Curl Bracket Extension holds a specific niche within the realm of digital text and programming.

How to type the symbol on Windows

Hold Alt and type 9130 on the numpad. Or use Character Map.

  1. Step 1: Determine the UTF-8 encoding bit layout

    The character has the Unicode code point U+23AA. In UTF-8, it is encoded using 3 bytes because its codepoint is in the range of 0x0800 to 0xffff.

    Therefore we know that the UTF-8 encoding will be done over 16 bits within the final 24 bits and that it will have the format: 1110xxxx 10xxxxxx 10xxxxxx
    Where the x are the payload bits.

    UTF-8 Encoding bit layout by codepoint range
    Codepoint RangeBytesBit patternPayload length
    U+0000 - U+007F10xxxxxxx7 bits
    U+0080 - U+07FF2110xxxxx 10xxxxxx11 bits
    U+0800 - U+FFFF31110xxxx 10xxxxxx 10xxxxxx16 bits
    U+10000 - U+10FFFF411110xxx 10xxxxxx 10xxxxxx 10xxxxxx21 bits
  2. Step 2: Obtain the payload bits:

    Convert the hexadecimal code point U+23AA to binary: 00100011 10101010. Those are the payload bits.

  3. Step 3: Fill in the bits to match the bit pattern:

    Obtain the final bytes by arranging the paylod bits to match the bit layout:
    11100010 10001110 10101010
