Description

The Unicode character U+22A6 represents the mathematical symbol for assertion, also known as the double colon (::). This symbol is commonly used in digital text, particularly within mathematical and computational contexts, to indicate that a statement or hypothesis should be taken as true without proof. While it may seem like a simple punctuation mark, its use can significantly impact the meaning of a statement or equation in mathematical discourse. The assertion symbol has cultural, linguistic, and technical significance across various domains such as computer programming, logic, and mathematics, where clear and precise communication of ideas is crucial. Its usage promotes clarity in these fields by distinguishing an assumed truth from a proven fact, facilitating effective collaboration among experts.

How to type the symbol on Windows

Hold Alt and type 8870 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+22A6. 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+22A6 to binary: 00100010 10100110. 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 10001010 10100110
