Description

U+2473, or CIRCLED NUMBER TWENTY, is a character from the Unicode standard that represents a numeral enclosed within a circle. Typical usage of this character in digital text includes its use in mathematical equations, scientific notation, and engineering calculations to denote values greater than 19. The symbol serves as an alternative to the standard Arabic numeral '20' and is commonly used in applications where a more visually distinct representation is desired. While it does not have any specific cultural or linguistic significance, its usage can help avoid ambiguity in certain contexts, such as programming languages, where it can be mistaken for the letter 'O'. In these cases, using CIRCLED NUMBER TWENTY ensures clarity and prevents potential errors.

How to type the symbol on Windows

Hold Alt and type 9331 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+2473. 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+2473 to binary: 00100100 01110011. 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:
