Description

The Unicode character U+2A4C, known as the Closed Union with Serifs, is a specialized typographic symbol used predominantly in mathematical and scientific texts for denoting certain types of logical operations or sets. Its primary role lies in digital text, where it often appears in technical documents, such as computer programming, engineering, or mathematics fields. In these contexts, the Closed Union with Serifs can be utilized to represent an intersection operation between two sets or relationships within a complex system. Although its usage may not be widespread among the general public, this symbol holds great importance for professionals and academicians in various technical disciplines. Its presence contributes significantly to clarity and precision in communication of concepts that would otherwise require lengthy explanations and more conventional symbols might not convey as effectively.

How to type the symbol on Windows

Hold Alt and type 10828 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+2A4C. 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+2A4C to binary: 00101010 01001100. 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 10101001 10001100
