Description

The Unicode character U+2474, known as PARENTHESIZED DIGIT ONE, is a typographic representation of the numeral "1" enclosed in parentheses. In digital text, this character is primarily utilized for various purposes such as creating subscripts, superscripts, and mathematical notations. It is often used to distinguish numerals within a text or equation from other elements, providing clarity and enhancing readability. Although U+2474 may seem like an obscure character, it plays a vital role in fields that require precise formatting of numerical data, including mathematics, computer programming, and scientific documents.

How to type the symbol on Windows

Hold Alt and type 9332 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+2474. 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+2474 to binary: 00100100 01110100. 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 10010001 10110100
