Description

The Unicode character U+293C, known as "TOP ARC CLOCKWISE ARROW WITH MINUS," serves a specific function in digital text, particularly within the domain of mathematics and computer programming. It is an important element used to represent an open interval notation in mathematical expressions. This symbol represents a clockwise rotation of an arc, with the negative sign indicating a counter-clockwise direction. Its presence in Unicode expands the range of symbols available for precise expression in text, enhancing the ability of programmers and mathematicians to convey complex ideas and relationships. It is often employed to denote a specific set of values or points within a mathematical model, making it an indispensable tool in fields such as computer science, engineering, physics, and other disciplines that rely on numerical representation and manipulation.

How to type the symbol on Windows

Hold Alt and type 10556 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+293C. 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+293C to binary: 00101001 00111100. 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 10100100 10111100
