Step 1: Determine the UTF-8 encoding bit layout
The character ℕ has the Unicode code point U+2115. 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+2115 to binary:
00100001 00010101. 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 10000100 10010101

Description
The Unicode character U+2115, known as the Double-struck Capital N, is a typographic symbol that plays a crucial role in digital text formatting. This character, often used in mathematical and scientific contexts, provides an alternative representation of the letter "N" with doubled strokes for clarity or emphasis. The Double-struck Capital N stands out due to its distinct, bold appearance, where it appears as if the letter has been traced twice, giving it a unique aesthetic that sets it apart from other characters in its category. Its usage is primarily found within the realms of computer science, engineering, and mathematics, where it may be employed in technical documents, diagrams, or equations for enhanced readability and visual distinction.
