Step 1: Determine the UTF-8 encoding bit layout
The character ▪ has the Unicode code point U+25AA. 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+25AA to binary:
00100101 10101010. 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 10101010

Description
The Unicode character U+25AA, also known as the Black Small Square, serves a crucial role in typography and digital text formatting. This character is part of the "Box Drawing" category within the Unicode Standard, which includes various symbols used to create boxes or borders around text or other elements within a document. The Black Small Square specifically represents one of the smaller square characters, often employed in pair with its counterparts U+25AB (White Small Square) and U+25AC (Black Small Circle). In digital texts, it is commonly utilized for aligning columns, delineating sections or tables, or as a visual guide to indicate spacing and alignment. While the Black Small Square itself does not hold any cultural or linguistic significance, its practical applications across different platforms and programming languages demonstrate the versatility and importance of Unicode in facilitating consistent and accurate digital text representation.
