Description

The Unicode character U+2989, also known as "Z NOTATION LEFT BINDING BRACKET," is a typographical symbol that holds significance in digital text, specifically within the domain of mathematics and computer science. In these contexts, it is primarily employed to denote structured information or expressions, often serving as delimiters in mathematical notations or programming languages. It represents a left-side binding bracket, corresponding to its right-side counterpart U+298A (Z NOTATION RIGHT BINDING BRACKET). Although the character may be less familiar compared to other widely used symbols, it remains an essential tool for ensuring accurate and unambiguous communication in fields where precise expression of ideas and data is crucial.

How to type the symbol on Windows

Hold Alt and type 10633 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+2989. 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+2989 to binary: 00101001 10001001. 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 10100110 10001001
