Step 1: Determine the UTF-8 encoding bit layout
The character ⣹ has the Unicode code point U+28F9. 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+28F9 to binary:
00101000 11111001. 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 10111001

Description
U+28F9, or Braille Pattern Dots-145678, is a character in the Unicode Standard that represents a single cell of a Braille pattern. In digital text, this character is used to convey information to visually impaired users who rely on Braille for reading and writing. It consists of six dots arranged in a 2x3 grid, with the first dot on the left and bottom representing position 1, and the last dot on the right and top representing position 6. Each possible combination of these dots corresponds to a different letter or symbol in Braille, making it a crucial component of digital braille transcription. While the Unicode character itself does not convey any specific meaning, its presence within a larger body of text can represent one of over 200 distinct Braille characters, allowing for a wide range of communication and information sharing across different languages and contexts.
