Step 1: Determine the UTF-8 encoding bit layout
The character ⟉ has the Unicode code point U+27C9. 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+27C9 to binary:
00100111 11001001. 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 10011111 10001001

Description
The Unicode character U+27C9, also known as the Superset Preceding Solidus, is a typographical symbol used in digital text. Its primary role is to indicate that one set of characters or symbols is a subset of another, with the solidus (/) serving as a separator between the superset and the subset. This character can be found in the Enclosed Alphanumeric Supplements block of Unicode, which includes various characters that are enclosed by a box-like shape. While this specific symbol doesn't have any notable cultural or linguistic significance, it plays an important role in technical writing, particularly in computer science and mathematics, where the concept of subsets and supersets is frequently used to explain relationships between different sets of elements.
