Description

The Unicode character U+2AC3, also known as SUBSET OF OR EQUAL TO WITH DOT ABOVE, is a mathematical symbol that plays a significant role in digital text, particularly within the realm of mathematics, computer science, and engineering. Its primary purpose is to denote a relation between two sets or values, indicating that one set or value is a subset of or equal to another. The inclusion of the dot above the symbol is a stylistic choice that enhances its visual appeal and legibility, making it easily distinguishable from similar symbols in digital text. Although it may not have a notable cultural, linguistic, or technical context beyond its mathematical applications, U+2AC3 remains an essential tool for accurate communication of complex concepts within the aforementioned fields. Its precise usage and presentation contribute to the clarity and comprehension of equations, algorithms, and logical structures in digital text, demonstrating the significance of typography and character design in facilitating effective communication across disciplines.

How to type the symbol on Windows

Hold Alt and type 10947 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+2AC3. 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+2AC3 to binary: 00101010 11000011. 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 10000011
