Step 1: Determine the UTF-8 encoding bit layout
The character ⢛ has the Unicode code point U+289B. 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+289B to binary:
00101000 10011011. 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 10011011

Description
The Unicode character U+289B, known as BRAILLE PATTERN DOTS-12458, is a crucial component in the Braille system used for tactile communication among visually impaired individuals. In digital text, this character represents one of the 63 possible patterns in the six-dot Braille cell, which allows representation of numbers, letters, and symbols through various combinations of raised dots. The pattern is composed of two horizontal rows of three dots each, with the dot positions numbered from top to bottom and left to right as 123, 456. BRAILLE PATTERN DOTS-12458 corresponds to the numeral '8' in Braille, an essential digit in both mathematical operations and everyday counting for blind users. The Braille system was invented by Louis Braille in 1821, significantly impacting the lives of visually impaired people worldwide by providing a means to read and write written language tactilely. This character demonstrates the universality and adaptability of Unicode, which facilitates cross-platform compatibility and accessibility for various languages and scripts, including Braille.
