Step 1: Determine the UTF-8 encoding bit layout
The character ⍀ has the Unicode code point U+2340. In UTF-8, it is encoded using 3 bytes because its codepoint is in the range of
0x0800
to0xffff
.
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 thex
are 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+2340 to binary:
00100011 01000000
. 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 10000000

Description
The Unicode character U+2340, also known as the APL Functional Symbol Backslash Bar, is a specialized typographic symbol used primarily in digital text applications. This character holds significant relevance within the realm of mathematical notation and computer programming, particularly within the domain of the esoteric programming language APL (A Programming Language). APL was developed by Charles Samuel "Chuck" Moore in 1966 as a vector-based programming language, which is still used today for its compactness, elegance, and efficiency. In APL notation, U+2340 serves as a functional symbol that represents the backslash bar operation, which performs element-wise multiplication. This operation is central to the computation of arrays in APL, making the character essential for coding and mathematical calculations within this unique language. Despite its specialized usage, U+2340 remains an important component in the broader landscape of digital text, showcasing the rich diversity and adaptability of Unicode characters in catering to various linguistic and technical needs.
