Step 1: Determine the UTF-8 encoding bit layout
The character ⍥ has the Unicode code point U+2365. 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+2365 to binary:
00100011 01100101. 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 10100101

Description
U+2365 is a unique character in the Unicode standard, representing the APL Functional Symbol Circle Diacritic (APL FUNCTIONAL SYMBOL CIRCLE DIAERESIS). This typographical symbol plays an essential role in digital text by enabling clear and precise communication across various technical contexts. The Circle Diacritic, as part of the APL (Algol-like Programming Language) functional symbols, is primarily used in mathematical and scientific notation to denote specific operations or functions. It is not tied to a particular language but serves as an international standard for expression in fields such as computer science, engineering, and advanced mathematics. The Circle Diacritic is a powerful tool in these disciplines due to its ability to concisely indicate the presence of a function or operation without cluttering the text with lengthy descriptions. The symbol's cultural and linguistic significance lies in its utility for enhancing global communication and understanding across various domains, where precise mathematical notations are critical for accurate knowledge transfer. Its use is not limited to any one culture or language, making it an essential addition to the Unicode standard for inclusive and effective digital text representation.
