Step 1: Determine the UTF-8 encoding bit layout
The character ◨ has the Unicode code point U+25E8. 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+25E8 to binary:
00100101 11101000. 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 10010111 10101000

Description
The Unicode character U+25E8, known as SQUARE WITH RIGHT HALF BLACK, is a typographical symbol used primarily in digital text for creating geometric shapes and borders. This symbol represents the right half of a square and when paired with its counterpart, U+25EC (SQUARE WITH LEFT HALF BLACK), it can create a complete black square. It finds extensive usage in technical documentation, such as flowcharts or diagrams, to illustrate concepts, divide sections, or indicate empty spaces for user input. The SQUARE WITH RIGHT HALF BLACK does not hold any specific cultural, linguistic, or symbolic significance; its primary purpose is a functional one within the context of digital text formatting and design.
