Step 1: Determine the UTF-8 encoding bit layout
The character ■ has the Unicode code point U+25A0. 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+25A0 to binary:
00100101 10100000
. 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 10100000

Description
The Unicode character U+25A0, known as the Black Square, holds a significant position in typography and digital text. It is commonly utilized to represent an area where other content will be inserted or to act as a placeholder for a graphic element within a document or website design. This character is part of the Box Drawing block in Unicode, which includes various shades and styles of lines and squares used to create simple graphics or layout structures within text. Despite its simplicity, the Black Square plays an essential role in modern digital communication, allowing for more effective organization and presentation of content across different platforms and devices. Its ubiquity highlights the importance of Unicode in standardizing character encodings and fostering global communication.
