Step 1: Determine the UTF-8 encoding bit layout
The character ⢪ has the Unicode code point U+28AA. 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+28AA to binary:
00101000 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 10100010 10101010

Description
U+28AA, known as BRAILLE PATTERN DOTS-2468, is a vital character in the realm of digital text for visually impaired individuals. This unicode symbol is an essential component of Braille, a tactile writing system that allows users to read and write through touch, as opposed to sight. The Braille pattern consists of six dots arranged in two rows of three, with each dot either raised or flat depending on whether it represents a "1" or "0". In the case of U+28AA, the pattern is represented by two dots raised (11) and four dots flat (00), corresponding to the binary number 010100 in Braille numeral system. This specific character holds a significant role in enabling communication for those who are blind or have low vision, making it an essential tool in empowering these individuals to access information and interact with the world around them. The unicode character U+28AA underscores the importance of inclusive digital communication, as it contributes to ensuring equal opportunities for all users, regardless of their physical abilities.
