Description

The Unicode character U+2AD4, also known as the Superset Above Subset symbol, is a typographic glyph that plays a significant role in digital text, particularly within mathematical and logical contexts. Its primary function is to visually represent the concept of a superset in relation to a subset, illustrating the idea that one set contains all elements of another set while also including additional elements. This symbol is particularly useful in computer science, mathematics, and logic where the concept of sets and their relationships are frequently employed. The Superset Above Subset character helps clarify complex relationships between different sets, enhancing readability and reducing misinterpretation.

How to type the symbol on Windows

Hold Alt and type 10964 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+2AD4. 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+2AD4 to binary: 00101010 11010100. 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 10010100
