Step 1: Determine the UTF-8 encoding bit layout
The character ⍂ has the Unicode code point U+2342. 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+2342 to binary:
00100011 01000010
. 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 10000010

Description
The Unicode character U+2342 represents the APL Functional Symbol Quad Backslash in digital text. This typographical symbol has a significant role in programming languages and mathematical notation systems. Specifically, it is used to signify the operation of backslashing or redefining a function in the context of APL (A Programming Language). Developed by Charles Wheelwright in 1962, APL is a high-level, array-oriented programming language known for its concise notation and efficient computation. Its unique symbol set, which includes U+2342 among others, has been influential in the development of modern computer languages and mathematical notations.
