Step 1: Determine the UTF-8 encoding bit layout
The character ⍅ has the Unicode code point U+2345. 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+2345 to binary:
00100011 01000101. 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 10000101

Description
The Unicode character U+2345 is known as the APL Functional Symbol Leftwards Vane. This symbol holds a significant role in digital text, particularly within the realm of programming and mathematical notation. In APL (a specialized programming language), this character represents the "leftward function" and is used to indicate the application of a function across multiple dimensions in an array. It is part of the APL Functional Symbols block introduced in Unicode 3.0, which comprises various characters used to denote specific mathematical functions and operations. Although it may not be commonly recognized outside of APL programming, the U+2345 symbol plays a critical role within this specialized context, facilitating efficient expression of complex operations for those familiar with its application.
