Step 1: Determine the UTF-8 encoding bit layout
The character ⊣ has the Unicode code point U+22A3. In UTF-8, it is encoded using 3 bytes because its codepoint is in the range of
0x0800to0xffff.
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 thexare the payload bits.UTF-8 Encoding bit layout by codepoint range Codepoint Range Bytes Bit pattern Payload length U+0000 - U+007F 1 0xxxxxxx 7 bits U+0080 - U+07FF 2 110xxxxx 10xxxxxx 11 bits U+0800 - U+FFFF 3 1110xxxx 10xxxxxx 10xxxxxx 16 bits U+10000 - U+10FFFF 4 11110xxx 10xxxxxx 10xxxxxx 10xxxxxx 21 bits Step 2: Obtain the payload bits:
Convert the hexadecimal code point U+22A3 to binary:
00100010 10100011. Those are the payload bits.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 10100011

Description
The Unicode character U+22A3 represents the Left Tack symbol (⊠), which is primarily used in digital text for mathematical expressions and symbolic notations. Its role is to denote an imaginary element that can be "tacked" onto other elements, often within the context of algebraic topology or homotopy theory. This specialized symbol serves a crucial function in these advanced fields of mathematics by illustrating the concept of a "pushout" or "amalgamated sum." The Left Tack symbol's significance extends beyond mathematics, as it highlights the versatility and importance of Unicode in accommodating an extensive range of characters and symbols to facilitate accurate communication across various disciplines.
