Step 1: Determine the UTF-8 encoding bit layout
The character ⣊ has the Unicode code point U+28CA. 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+28CA to binary:
00101000 11001010. 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 10001010

Description
U+28CA (BRAILLE PATTERN DOTS-2478) is a character used in Unicode to represent a specific Braille pattern. This character holds a significant role in digital text for the visually impaired, as it helps them read and interpret written content through touch using Braille devices. The Braille system was invented by Louis Braille in 1821 and has since become an essential tool for those with visual impairments. Each Braille pattern is composed of six dots arranged in a grid of two rows and three columns, and U+28CA represents one such configuration. This particular character is used to represent the letter "o" or "u" in various languages that employ the Braille alphabet. As technology advances, the use of Braille characters like U+28CA becomes increasingly crucial for accessibility, fostering inclusivity and communication across diverse populations.
