Step 1: Determine the UTF-8 encoding bit layout
The character ⍲ has the Unicode code point U+2372. 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+2372 to binary:
00100011 01110010. 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 10110010

Description
The Unicode character U+2372, or APL FUNCTIONAL SYMBOL UP CARET TILDE, is a typographical symbol predominantly used in digital text to represent mathematical or scientific concepts. It serves as an integral component of the Advanced Programming Language (APL), a two-dimensional array programming language developed by Kenneth E. Iverson in 1962. In APL, U+2372 is used to denote a specific mathematical operation known as "up caret tilde," which is a function that combines the concepts of matrix multiplication and element-wise binary operations. This character's unique role within the APL language highlights its significance in both linguistic and technical contexts, particularly for programmers and mathematicians who utilize it to express complex mathematical relationships concisely.
