Step 1: Determine the UTF-8 encoding bit layout
The character ⢴ has the Unicode code point U+28B4. 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+28B4 to binary:
00101000 10110100. 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 10110100

Description
U+28B4 (Braille Pattern Dots-3568) is a crucial character within the Unicode standard, specifically designed for use in digital text. Its primary role lies in enabling communication through Braille, a tactile writing system employed by individuals with visual impairments or blindness. This character is part of a larger set of Braille patterns that represent letters, numbers, and symbols in the Braille alphabet. Each pattern consists of six positions, called dots, which can be raised or not raised to create a distinct character. U+28B4 corresponds to Pattern Dots-3568, representing the letter 'o' in the English Braille alphabet. Its inclusion in digital text facilitates accessibility and communication for users relying on Braille, ensuring inclusivity across various media formats. By providing a standardized representation of tactile characters within Unicode, U+28B4 contributes to bridging the gap between visual and tactile information, promoting literacy and social integration for those with vision loss.
