Step 1: Determine the UTF-8 encoding bit layout
The character ⓪ has the Unicode code point U+24EA. 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+24EA to binary:
00100100 11101010. 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 10101010

Description
The Unicode character U+24EA, known as the "CIRCLED DIGIT ZERO," is a typographic symbol used in digital text to represent the numeral zero within a circular format. Its typical usage lies primarily within mathematical equations and scientific notations, where it is often employed to signify an absence of value or a starting point for counting. Despite its infrequent use compared to other digits, the Circled Digit Zero holds significance in certain technical contexts, such as computer programming and data visualization, where distinct visual cues are necessary for improved comprehension and clarity. Although it has limited cultural, linguistic, or technical relevance in general usage, the Circled Digit Zero remains a valuable tool within specialized fields that require precise typographic representation.
