Step 1: Determine the UTF-8 encoding bit layout
The character ⍉ has the Unicode code point U+2349. 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+2349 to binary:
00100011 01001001. 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 10001101 10001001

Description
U+2349 APL Functional Symbol Circle Backslash is a character from the APL (Association for Computing Machinery's Special Character Set) functional symbol set in Unicode. This specific symbol represents a circle with a diagonal line through it, symbolizing a mathematical function that has been reversed or negated. Typically used in digital text, particularly within scientific and mathematical domains, it serves as a functional glyph for computational notation. Its usage aligns with APL's original design, which sought to create a language of symbols and mathematical functions rather than words. While not widely recognized outside these specific contexts, the U+2349 symbol holds significant cultural relevance in the niche world of programming languages and advanced mathematics.
