Step 1: Determine the UTF-8 encoding bit layout
The character ∻ has the Unicode code point U+223B. 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+223B to binary:
00100010 00111011. 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 10001000 10111011

Description
The Unicode character U+223B, known as HOMOTHETIC (ℬ), is a typographical symbol used primarily in mathematical and scientific notation. In digital text, it represents the concept of "homothetic scaling" or transformation, which involves resizing an object while preserving its proportions. This symbol is particularly useful in geometry and computer graphics for illustrating scale transformations and maintaining similarities between shapes during scaling operations. While not widely used in everyday language, U+223B has a specific role within the realm of technical and specialized discourse.
