Description

The Unicode character U+2312 is known as the ARC character. It serves a significant role in typography and digital text formatting by representing an arc shape that can be used to illustrate or denote a curved line or segment. This symbol is particularly useful for displaying arcs in mathematical equations, technical drawings, and various types of graphical content where the concept of an arc is essential. Despite not being as widely used as other symbols due to its specialized application, it holds a notable place in digital text and typography, providing a clear visual representation of an arc that helps improve readability and understanding of curved lines in various contexts.

How to type the symbol on Windows

Hold Alt and type 8978 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+2312. 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+2312 to binary: 00100011 00010010. 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 10001100 10010010
