Step 1: Determine the UTF-8 encoding bit layout
The character ⍜ has the Unicode code point U+235C. 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+235C to binary:
00100011 01011100
. 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 10011100

Description
The Unicode character U+235C, APL Functional Symbol Circle Underscore, is a specialized typographical symbol used primarily within the context of digital text related to the Algorithmic Language Programming (APL) domain. This symbol finds its origins in the APL language developed by Sir Christopher Strachey and Kenneth E. Iverson, which was designed for scientific computation and mathematical expression. In APL programming, the character is employed as a functional indicator, signaling the presence of a function within an expression or code block. It plays a pivotal role in denoting scoping levels, creating anonymous functions, and providing syntactical clarity to users familiar with APL's unique notation system. Despite its niche usage within the realm of APL programming, U+235C serves as a testament to the rich diversity of typographical symbols available within Unicode for specific applications and contexts.
