Step 1: Determine the UTF-8 encoding bit layout
The character ℼ has the Unicode code point U+213C. 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+213C to binary:
00100001 00111100. 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 10111100

Description
The Unicode character U+213C, known as the DOUBLE-STRUCK SMALL PI (ℌ), is a typographical symbol used primarily in digital text for its distinct appearance and mathematical representation. In computer typesetting, it is often employed within various scientific, technical, and engineering fields to denote specific variables or parameters in equations, often differentiating them from other symbols in the text. Its double-struck format provides clear visual distinction and helps avoid confusion with similar single-struck symbols. Although not a widely used character, U+213C holds significance in certain specialized contexts where precise typography and clear communication are paramount.
