Description

The Unicode character U+23AB, known as the Right Curly Bracket Upper Hook, is a specialized symbol often used in computer programming and digital text. Its primary role is to indicate the beginning of a group or a section of code that should be treated as a single entity. This character is particularly useful in mathematical expressions, where it can enclose a set of variables, operations, or functions. Although this character isn't widely used in everyday language, it holds significance in programming languages like C++ and Perl due to its ability to create a scope for variables. It is part of the 'Miscellaneous Technical' category in Unicode, which includes various symbols used in technology and computing.

How to type the symbol on Windows

Hold Alt and type 9131 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+23AB. 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+23AB to binary: 00100011 10101011. 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 10101011
