Description

The Unicode character U+2A5E represents the LOGICAL AND WITH DOUBLE OVERBAR symbol. This typographic character is primarily used in digital text for its specific mathematical and logical representation. It serves to denote a logical conjunction that implies a strict equivalence relationship between two binary values or propositions, where both values must be true simultaneously for the conjunction to hold true. The double overbar above the symbol visually emphasizes this strictness of the logical operation. While it may not have a direct cultural, linguistic, or technical context, the LOGICAL AND WITH DOUBLE OVERBAR is essential in mathematical and programming applications that rely on precise binary logic operations. Its role is vital in ensuring accuracy and clarity when conveying complex logical relationships within digital text formats.

How to type the symbol on Windows

Hold Alt and type 10846 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+2A5E. 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+2A5E to binary: 00101010 01011110. 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 10101001 10011110
