Description

The Unicode character U+2AC9, known as SUBSET OF ABOVE ALMOST EQUAL TO, is a unique symbol used in digital text to denote a specific mathematical relationship between two quantities. It is particularly useful in mathematical notation and formulae where precise representations of relationships are required. This character has been designed for use in digital texts such as mathematical documents, scientific literature, and engineering reports, where exact representation and clarity of relationships are critical. Despite its limited usage due to the specialized nature of its role, it plays a significant part in facilitating accurate communication of complex ideas within specific technical contexts. Its inclusion in the Unicode standard ensures global accessibility and interoperability across various platforms and devices, thereby enhancing the precision and clarity of digital text representations in these niche areas.

How to type the symbol on Windows

Hold Alt and type 10953 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+2AC9. 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+2AC9 to binary: 00101010 11001001. 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 10101011 10001001
