Description

The Unicode character U+2480, also known as the Parenthesized Number Thirteen (④), holds a significant role in digital text as it is used to represent the numeral '13' within parenthesis brackets. This unique symbol is part of the "Number Forms" block introduced in Unicode 5.1, which contains various typographic representations of numbers. U+2480 is particularly useful for those working in fields such as information technology, programming, or statistics where clear and concise representation of numerical data is crucial. While it may seem like a minor detail to some, this character helps to improve the readability and clarity of digital text by visually distinguishing numerals from other characters.

How to type the symbol on Windows

Hold Alt and type 9344 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+2480. 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+2480 to binary: 00100100 10000000. 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:
