Step 1: Determine the UTF-8 encoding bit layout
The character ⍎ has the Unicode code point U+234E. 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+234E to binary:
00100011 01001110
. 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 10001110

Description
The Unicode character U+234E represents the APL Functional Symbol Down Tack Jot (⊚). This symbol is primarily used in digital text to represent a mathematical operation known as "down tacking," which is commonly employed in the programming language APL (A Programming Language). Developed by Charles L. Barr and Kenneth E. Iverson, APL was specifically designed for mathematical computation and data manipulation. The Down Tack Jot symbol holds significant importance in APL, as it signifies a specific operation that resembles "reversing the order of factors" in an expression. While this character may not be widely recognized outside of specialized mathematical or technical contexts, its use within APL contributes to the language's unique and powerful set of operations that streamline complex computations.
