Step 1: Determine the UTF-8 encoding bit layout
The character ⓭ has the Unicode code point U+24ED. 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+24ED to binary:
00100100 11101101. 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 10010011 10101101

Description
The Unicode character U+24ED, known as the NEGATIVE CIRCLED NUMBER THIRTEEN, serves a specialized purpose in digital text, particularly within mathematical and scientific documentation. It is commonly used to represent the negative value of thirteen when displayed within subscripts or superscripts for clearer contextualization. In these instances, the character facilitates readability and comprehension by visually indicating the negative sign in close proximity to the numerical value it modifies. Although this specific symbol may not be widely utilized in everyday language, its presence within specialized fields underscores the versatility of Unicode's extensive character set and contributes to the precise communication necessary for technical discourse.
