Step 1: Determine the UTF-8 encoding bit layout
The character ⠄ has the Unicode code point U+2804. 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+2804 to binary:
00101000 00000100. 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 10100000 10000100

Description
U+2804 (BRAILLE PATTERN DOTS-3) is a Unicode character representing the third pattern of Braille dots. In digital text, it serves as an essential element for converting written language into tactile information, enabling visually impaired individuals to read through touch. This specific character, when combined with other dot patterns, forms various letters and symbols in the Braille alphabet. Developed by Louis Braille in 1821, the Braille system has been widely adopted worldwide as a critical tool for blind and low-vision people to access and communicate effectively in written form. U+2804 contributes significantly to digital inclusion, bridging the gap between sighted and visually impaired users in online environments and digital text formats.
