Step 1: Determine the UTF-8 encoding bit layout
The character ⑨ has the Unicode code point U+2468. 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+2468 to binary:
00100100 01101000. 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 10010001 10101000

Description
The Unicode character U+2468 represents the Circled Digit Nine (⡈). This typographical symbol is commonly used in various applications within digital text to distinguish numeric values and denote quantities, indices, or iterations. Unlike other digits that are usually found in the Basic Latin block of Unicode characters, the Circled Digit Nine belongs to the Miscellaneous Technical block (U+2400 - U+24FF). In technical documents and mathematical expressions, it serves as a visual alternative to the standard numeral '9', helping to avoid confusion with similar digits or symbols. The Circled Digit Nine is particularly useful in scientific notations, indexing systems, and enumeration, where its distinct form ensures clarity of information and minimizes potential misinterpretation.
