Step 1: Determine the UTF-8 encoding bit layout
The character ⠈ has the Unicode code point U+2808. 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+2808 to binary:
00101000 00001000. 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 10001000

Description
U+2808, also known as Braille Pattern Dots-4, is a crucial character in the Unicode standard, specifically designed for digital text representation of Braille characters. This unique character represents one of the six different patterns in the Braille alphabet, which is an essential system used primarily by individuals who are visually impaired to read and write. Each pattern consists of raised dots arranged in a 3x2 grid, where each dot's presence or absence corresponds to a specific letter, number, or symbol. In the case of Braille Pattern Dots-4, it is utilized for the representation of various characters, including letters, numerical values, and punctuation marks. The Braille system's cultural, linguistic, and technical significance lies in its ability to democratize access to written communication for the visually impaired, thereby fostering inclusivity and literacy for all individuals.
