Step 1: Determine the UTF-8 encoding bit layout
The character ⢩ has the Unicode code point U+28A9. 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+28A9 to binary:
00101000 10101001. 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 10101001

Description
U+28A9, also known as Braille Pattern Dots-1468, is a critical character in the field of typography, particularly within digital text and communication systems designed for visually impaired individuals. It is an integral element of the Braille writing system, which was developed by Louis Braille in 1821 to enable blind people to read and write through touch. Each Braille cell, represented by U+28A9, comprises a combination of six raised dots arranged in a 3x2 grid pattern. These dots can be either raised or flat, depending on the presence or absence of a character, thereby encoding letters, numbers, and symbols in a tactile manner. The Braille Pattern Dots-1468 character is particularly significant as it forms the basis for various other patterns, making it an essential building block for the entire Braille alphabet and numeral system. In the context of digital text, U+28A9 ensures inclusivity and accessibility in communication, allowing visually impaired users to engage with information through assistive technologies like Braille displays or refreshable Braille embossers.
