Step 1: Determine the UTF-8 encoding bit layout
The character ⍸ has the Unicode code point U+2378. 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+2378 to binary:
00100011 01111000. 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 10111000

Description
The Unicode character U+2378, commonly referred to as the APL Functional Symbol Iota Underbar, holds a significant role in digital text, particularly within the realm of programming and computer science. This character is predominantly used in the context of the APL (Array Programming Language) programming language, where it represents the Iota operator, which denotes a specific matrix operation in mathematical terms. The Iota operator is highly valuable for its ability to facilitate concise and efficient representation of complex matrix expressions, streamlining computational processes and optimizing coding syntax. Although the APL Functional Symbol Iota Underbar may not be widely recognized outside of specialized programming communities, it remains an indispensable tool within the niche of array-based computation.
