Description

The Unicode character U+2961, known as the "DOWNWARDS HARPOON WITH BARB LEFT FROM BAR", is a typographical symbol used primarily in digital text for mathematical or scientific notation. It represents a specific type of mathematical operator that subtracts a variable from a sequence represented by a bar. In its usage, it often signifies an action in linear algebra where the left barb is subtracted from the overall sequence, representing a directional change in a complex mathematical equation. While not commonly used outside of these specialized contexts, U+2961 plays a crucial role in accurately conveying information within these specific fields. As with many Unicode characters, its usage is determined by the needs of the discipline and the requirements of the document or digital communication it serves.

How to type the symbol on Windows

Hold Alt and type 10593 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+2961. 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+2961 to binary: 00101001 01100001. 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 10100101 10100001
