Step 1: Determine the UTF-8 encoding bit layout
The character ⍈ has the Unicode code point U+2348. 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+2348 to binary:
00100011 01001000
. 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:

Description
The Unicode character U+2348, known as the "APL FUNCTIONAL SYMBOL QUAD RIGHTWARDS ARROW," is a specialized typographic symbol primarily used in digital text within mathematical and programming contexts. It represents a rightwards arrow with a quadrant-like shape, indicating a function or operation that applies to quadrants of a space or plane. This character plays an essential role in APL (A Programming Language), which is a high-level, array-oriented, and concise programming language developed by Kenneth E. Iverson in the 1960s. APL is predominantly used for scientific computing, statistical analysis, and other complex mathematical applications due to its unique syntax and powerful capabilities. The U+2348 symbol, along with several other similar arrow symbols, facilitates concise expression of complex mathematical notations, aiding in the communication of intricate algorithms and functions within these domains.
