Step 1: Determine the UTF-8 encoding bit layout
The character ⓱ has the Unicode code point U+24F1. 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+24F1 to binary:
00100100 11110001. 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 10110001

Description
U+24F1, also known as the Negative Circled Number Seventeen, is a typographical character used predominantly in digital text for mathematical notation and equation representation. This symbol holds significant value in various fields such as computer programming, mathematics, and engineering, where it serves to denote negative numbers with a visual emphasis on their sign. While it may not have any specific cultural, linguistic, or technical contexts that are unique to itself, the character plays an essential role in conveying the concept of negative value clearly and efficiently. It contributes to the accuracy and clarity of text by visually distinguishing negative numbers from positive ones, thereby reducing potential misunderstandings in digital communication.
