Step 1: Determine the UTF-8 encoding bit layout
The character □ has the Unicode code point U+25A1. 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+25A1 to binary:
00100101 10100001. 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 10010110 10100001

Description
The Unicode character U+25A1, commonly known as the WHITE SQUARE, serves a variety of purposes within digital text. This typographical element is often employed for creating borders, grids, or spacers in web pages, documents, and applications. Due to its transparency, it can be used to separate sections, align columns, or create a visual hierarchy without significantly impacting the overall design aesthetic. The WHITE SQUARE has no cultural or linguistic significance but is technically essential for designers and developers who seek precise control over layout and spacing in their digital creations. Its versatility and utility make it an indispensable tool within modern typography and web development.
