Step 1: Determine the UTF-8 encoding bit layout
The character ⨰ has the Unicode code point U+2A30. 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+2A30 to binary:
00101010 00110000. 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 10101000 10110000

Description
The Unicode character U+2A30 represents the "MULTIPLICATION SIGN WITH DOT ABOVE" (⊚). In digital text, this symbol is used to denote multiplication and is often found in mathematical equations and expressions. Its presence above the baseline helps distinguish it from other similar symbols like the multiplication sign (×) and the division slash (⁄). Though primarily used in technical and scientific contexts, the character can also be found in various cultural and linguistic settings where unique or alternative symbols for multiplication are preferred. The Unicode Consortium, responsible for the development and maintenance of the Unicode Standard, has included this character to support a diverse range of typographical needs across different languages and scripts, demonstrating the importance of inclusive and accurate representation in digital text.
