Description

The Unicode character U+215F is known as the Fraction Numerator One (∟), which is commonly used to denote the numerator in a fraction. In digital text, it serves an essential role in representing fractions accurately, particularly for mathematical and scientific content where precise notation is crucial. The character's usage can be traced back to its inclusion in the typographical symbol set of the American Standard Code for Information Interchange (ASCII), further highlighting its importance in digital communication. While not directly tied to a specific cultural or linguistic context, U+215F contributes to clarity and precision in written language across various fields, including computer programming, mathematics, and technical documentation.

How to type the symbol on Windows

Hold Alt and type 8543 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+215F. 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+215F to binary: 00100001 01011111. 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 10000101 10011111
