Step 1: Determine the UTF-8 encoding bit layout
The character ⓞ has the Unicode code point U+24DE. 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+24DE to binary:
00100100 11011110. 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 10011110

Description
U+24DE is a character from the Unicode Standard that represents the circled Latin small letter "o" (CIRCLED LATIN SMALL LETTER O). This typographical symbol is used in various digital text applications, primarily for mathematical notations, chemical formulas, and computer programming. The circled letter is crucial in differentiating variables or identifiers that might otherwise appear the same if written in lowercase. In its cultural context, the usage of U+24DE in digital text can be traced back to the need for clearer communication in scientific texts, programming languages, and chemical formulas. Its use ensures better understanding among readers who may interpret lowercase "o" differently in certain contexts, reducing confusion and errors. Technically speaking, U+24DE is part of a set of characters known as "Circled Alphabetic Supplement" (U+2470-24FE) introduced in Unicode 3.1 to address the need for more symbols in mathematical notations and programming languages. The introduction of these circled alphabets expanded the versatility of the Unicode Standard, allowing users to create clearer and more accurate digital text.
