Description

The Unicode character U+2451 represents the Blackboard Bold Fraction 1/2 (๐‘›). This character is primarily used in digital text for mathematical notations, particularly in computer algebra systems and typesetting software. It serves as a bold representation of the fraction one-half, which is commonly used in various branches of mathematics and scientific disciplines such as physics, engineering, and computer science. The Blackboard Bold Fraction 1/2 is notable for its distinct appearance, as it combines the properties of blackboard bold fonts (a style of boldface type often used in mathematical notation) with those of fractions, making it more visually appealing and easier to read than standard fraction representations. This character adheres to the standards set by the Unicode Consortium, ensuring its accurate and consistent usage across multiple platforms and software applications.

How to type the โ‘‘ symbol on Windows

Hold Alt and type 9297 on the numpad. Or use Character Map.

  1. Step 1: Determine the UTF-8 encoding bit layout

    The character โ‘‘ has the Unicode code point U+2451. 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+2451 to binary: 00100100 01010001. 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 10010001
