Description

U+2A8B is a specific Unicode character known as LESS-THAN ABOVE DOUBLE-LINE EQUAL ABOVE GREATER-THAN. This unique symbol is part of the Miscellaneous Technical (U+2700–U+27BF) block of characters in the Unicode Standard, which includes a wide range of typographic symbols and mathematical notations. Its typical usage or role in digital text is to serve as a mathematical operator, specifically representing a double-line inequality that can be read as "less than or equal to" when combined with the greater-than sign (U+2A8B and U+003E respectively). This character has particular relevance in computer science and programming, where it is often used in algorithms and logical expressions. Although its usage may seem niche, this symbol plays a significant role in ensuring clarity and accuracy in technical documents, mathematical formulas, and coding contexts. The LESS-THAN ABOVE DOUBLE-LINE EQUAL ABOVE GREATER-THAN character contributes to the precision of communication in these fields by providing a clear visual representation of the relationship between values or expressions.

How to type the symbol on Windows

Hold Alt and type 10891 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+2A8B. 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+2A8B to binary: 00101010 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 10101010 10001011
