Step 1: Determine the UTF-8 encoding bit layout
The character ⢟ has the Unicode code point U+289F. 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+289F to binary:
00101000 10011111. 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 10011111

Description
The character U+289F, known as Braille Pattern Dots-123458, plays a significant role in the realm of digital text by representing one of the six possible combinations of raised dots used to encode letters and numbers within the Braille system. Developed by Louis Braille in 1821, this tactile writing system is primarily utilized by individuals with visual impairments, enabling them to read and write independently. The Braille Pattern Dots-123458 specifically corresponds to the letter 'o' in Grade 2 Braille or the number '0' in Braille numerals. In digital text, U+289F is used to maintain accessibility by ensuring that content is perceivable through assistive technologies like Braille displays and screen readers. It demonstrates a commitment to inclusivity and equal access to information across various formats and platforms.
