Step 1: Determine the UTF-8 encoding bit layout
The character ⣿ has the Unicode code point U+28FF. 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+28FF to binary:
00101000 11111111. 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 10111111

Description
U+28FF is the Unicode character code for Braille Pattern Dots-12345678, a standardized representation in digital text used to convey information for individuals with visual impairments or blindness. This character consists of six dot positions arranged in a 2x3 grid, allowing it to represent letters, numbers, and symbols in the Braille writing system. The dots can be either raised or flat, depending on the specific character being represented. In digital text, U+28FF is crucial for ensuring accessible communication across various platforms, as it enables visually impaired users to access written information through their preferred method of reading: touch rather than sight. The Braille writing system, including its digital representation in Unicode, bridges the gap between those with and without visual impairments, fostering inclusivity and facilitating universal literacy.
