Step 1: Determine the UTF-8 encoding bit layout
The character ⍷ has the Unicode code point U+2377. 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+2377 to binary:
00100011 01110111. 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 10110111

Description
The Unicode character U+2377, also known as APL Functional Symbol Epsilon Underbar, is a specialized mathematical symbol used in the programming language of Applied Mathematics. It serves an important role in digital text by representing the concept of a functional relationship between two variables, which is a fundamental principle in calculus and related fields. The character is part of the ASCII-compatible encoding (ACE) set, which extends the standard ASCII character set to include more mathematical and technical symbols. While its usage is highly specialized, it plays an important role in precise communication within these disciplines, where exact notation can be crucial for conveying complex ideas accurately. In summary, U+2377 is a critical tool for mathematicians, engineers, and computer scientists working with Applied Mathematics, ensuring the clear representation of functional relationships in digital text.
