Step 1: Determine the UTF-8 encoding bit layout
The character ⓵ has the Unicode code point U+24F5. 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+24F5 to binary:
00100100 11110101. 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 10110101

Description
The Unicode character U+24F5, known as the DOUBLE CIRCLED DIGIT ONE, is a typographic symbol commonly used in digital text for representing numeric values in specific contexts. This unique character is part of the Unicode range reserved for "Combining Diacritical Marks for Symbols" and provides an alternative visual representation of the digit one with a double circle surrounding it. Its primary role is to help distinguish numeric values in a text where multiple digits or symbols may be present, enhancing readability and reducing ambiguity. The character does not have any direct cultural, linguistic, or technical context associated with it, but its use can be observed in various technical documents, mathematical equations, or software interfaces that require clear distinction of numerical values.
