Step 1: Determine the UTF-8 encoding bit layout
The character ∎ has the Unicode code point U+220E. 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+220E to binary:
00100010 00001110. 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 10001000 10001110

Description
The Unicode character U+220E, known as the "End of Proof" mark (❋), is a typographical symbol that primarily serves a technical function in digital text. Its usage is typically found in typesetting and proofreading processes for printed materials, particularly in the publishing industry. The End of Proof mark signifies the end of a sequence of characters or elements within a given layout or document, indicating a point where review and adjustment can cease until the next section begins. This allows for efficient organization and tracking during the proofreading stage, ensuring accuracy and reducing errors in final published work. Although its usage is largely technical, the End of Proof mark may also hold cultural significance for those in the printing and publishing industries, as it represents a milestone in the creation process of printed materials.
