Step 1: Determine the UTF-8 encoding bit layout
The character ⣐ has the Unicode code point U+28D0. 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+28D0 to binary:
00101000 11010000. 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 10100011 10010000

Description
U+28D0 Braille Pattern Dots-578 is a character in the Unicode Standard that represents one of the 63 possible patterns used in Braille notation, which is a tactile writing system employed by visually impaired individuals for reading and communication. In digital text, it serves as an essential component for rendering Braille content, enabling blind users to access information through their sense of touch using Braille displays or refreshable Braille embossers. As part of the Unified English Braille (UEB) system, it adheres to strict rules governing the arrangement of raised dots in a 3x2 matrix, where each pattern corresponds to a letter, numeral, or symbol. The character's significance lies not only in its role within digital text but also as a vital tool that empowers individuals with visual impairments to effectively engage with written materials and contribute to linguistic and cultural exchanges.
