Step 1: Determine the UTF-8 encoding bit layout
The character ⣔ has the Unicode code point U+28D4. 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+28D4 to binary:
00101000 11010100. 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 10010100

Description
U+28D4, also known as Braille Pattern Dots-3578, is a crucial character in the Unicode standard that plays an indispensable role in digital text. This character represents one of the six dots in the Braille system used for tactile reading and writing by those who are visually impaired. The Braille pattern consists of a 2x3 grid of raised or embossed dots, where each dot can be either raised (indicated as "1") or not raised ("0"), creating 2^6 or 64 possible combinations. Each combination represents a specific character, number, or punctuation mark in the Braille alphabet, which allows visually impaired individuals to read and write text independently. The character U+28D4 specifically corresponds to the pattern "135-102" in the standard six-dot Braille configuration, with two raised dots in the first column, no dot in the second column, one raised dot in the third column, and one raised dot in the fourth column. This character is a vital component of digital text for accessibility purposes, ensuring that information can be read by both sighted and visually impaired users.
