Step 1: Determine the UTF-8 encoding bit layout
The character has the Unicode code point U+244F. 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+244F to binary:
00100100 01001111. 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 10010001 10001111

Description
The Unicode character U+244F is a typographic symbol known as the "Black Square" (CHARACTER 244F). It is a block element used primarily in digital text for design purposes, such as in layout grids or web design to create white space, as it appears as a transparent background when rendered. The Black Square does not represent any specific cultural, linguistic, or technical symbolism and has no inherent meaning. However, its usage can help with alignment and spacing within digital text, ensuring consistency and readability across different platforms and devices.
