Step 1: Determine the UTF-8 encoding bit layout
The character ␣ has the Unicode code point U+2423. 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+2423 to binary:
00100100 00100011. 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 10010000 10100011

Description
The Unicode character U+2423, known as the Open Box (◻), plays a crucial role in typography and digital text by representing an empty, rectangular container that can be used to symbolically encapsulate or enclose various elements of content. This versatile symbol is frequently employed in programming languages, graphical user interfaces, and design applications to visually organize and separate information, guiding users' attention and enhancing the readability of digital text. The Open Box character is part of a broader set of Block Elements in Unicode, which also includes the Shaded Box (◽), the Checkerboard (▮), and other similar symbols used for visual organization and emphasis. By avoiding the use of fluff and focusing on accuracy, U+2423 provides a consistent and universally recognized means of conveying these essential organizational functions across various platforms, applications, and languages, facilitating efficient communication and design in the digital world.
