Description

The Unicode character U+2B8D, also known as the Anticlockwise Triangle-Headed Bottom U-Shaped Arrow, is a specialized typographical symbol that plays a crucial role in digital text. Its primary function is to depict an arrow pointing downwards and curving anticlockwise at its tip, resembling a U shape. This character is predominantly used in mathematical expressions, particularly those involving vector calculus or geometry. It helps to clearly indicate the direction of vectors, specifically when defining rotational transformations or expressing rotational matrix operations in a two-dimensional space. The Anticlockwise Triangle-Headed Bottom U-Shaped Arrow symbol has no notable cultural or linguistic significance, and its usage is primarily confined to technical contexts such as mathematics, computer science, and engineering. Its presence in digital text ensures the accurate communication of complex concepts and processes, thereby contributing to clarity and precision in these specialized fields.

How to type the symbol on Windows

Hold Alt and type 11149 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+2B8D. 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+2B8D to binary: 00101011 10001101. 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 10101110 10001101
