Step 1: Determine the UTF-8 encoding bit layout
The character ⠂ has the Unicode code point U+2802. 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+2802 to binary:
00101000 00000010. 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 10000010

Description
U+2802, known as Braille Pattern Dots-2, is a crucial character in the Unicode standard, playing a vital role in digital text for visually impaired individuals. This symbol forms part of the Braille alphabet, which was developed by Louis Braille in 1821 to enable communication through tactile reading. Each Braille character consists of six raised or embossed dots arranged in a rectangular grid of two columns and three rows. The configuration of these dots represents different letters, numbers, or symbols, depending on the pattern used. In the case of U+2802, it corresponds to the Braille pattern Dots-2, which is typically used to represent specific letters, such as "i" in English or "e" in French. The use of this character and others in digital text helps maintain accessibility across various platforms and devices for blind and visually impaired users, ensuring equal opportunities in education, communication, and information exchange.
