Description

The Unicode character U+2282, commonly referred to as "SUBSET OF," serves a significant function in mathematical notation and symbolic representations within digital text. This typographic character is primarily employed to denote the subset relationship between two sets or collections of items. It is frequently utilized in mathematical expressions and set theory, showcasing the inclusion of elements from one set within another. While U+2282 is not culturally specific, it holds considerable importance in linguistic contexts, particularly within STEM fields, where accurate representation of relationships between sets is crucial for conveying complex ideas and calculations. The SUBSET OF symbol plays a vital role in ensuring clear communication and understanding among professionals and scholars in these areas.

How to type the symbol on Windows

Hold Alt and type 8834 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+2282. 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+2282 to binary: 00100010 10000010. 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 10000010
