Description

U+218B, known as the "Turned Digit Three," is a Unicode character that holds a unique position in the realm of digital text. This character is not frequently used but has specific roles within linguistic and technical contexts. Its primary purpose lies in representing a three-dimensional, rotated version of the digit '3', often employed in typography to convey a sense of depth or perspective. The Turned Digit Three has its origins in typewriter design, where it was used in mathematical expressions, engineering drawings, and other contexts requiring a distinct representation of the number '3'. Although not commonly seen in modern digital texts, it remains an important symbol for preserving historical typographic practices and serves as a useful tool in certain niche applications.

How to type the symbol on Windows

Hold Alt and type 8587 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+218B. 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+218B to binary: 00100001 10001011. 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 10000110 10001011
