Step 1: Determine the UTF-8 encoding bit layout
The character ⠡ has the Unicode code point U+2821. 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+2821 to binary:
00101000 00100001. 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 10100000 10100001

Description
U+2821 is the Unicode code point for Braille Pattern Dots-16, a character widely used in digital text for representing individual cells of braille patterns. This symbol plays a crucial role in facilitating communication for visually impaired individuals by encoding alphabetic and numerical characters into tactile patterns that can be read using touch. The braille system was developed by Louis Braille in the early 19th century, making it an essential tool in modern accessibility efforts. In digital text, U+2821 helps to maintain consistency and accuracy across various platforms, ensuring that content is universally accessible to those who rely on braille for communication. Its usage contributes significantly to promoting inclusivity and equal opportunities in education, literature, and technology for the visually impaired community.
