Step 1: Determine the UTF-8 encoding bit layout
The character ⢤ has the Unicode code point U+28A4. 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+28A4 to binary:
00101000 10100100. 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 10100100

Description
U+28A4 (Braille Pattern Dots-368) is a character in the Unicode Standard, specifically designed for use in digital text representation of Braille characters. This character represents one of the six Braille dots arranged in a 3x2 matrix pattern, used to encode various letters, numbers, and symbols within the Braille writing system. Developed by Louis Braille in the early 19th century, this tactile system enables visually impaired individuals to read and write using raised dots as an alternative to traditional print text. In digital formats, characters such as U+28A4 play a crucial role in ensuring accessibility for users with visual impairments by facilitating the accurate conversion of Braille content into various formats and vice versa.
