Step 1: Determine the UTF-8 encoding bit layout
The character ⣽ has the Unicode code point U+28FD. In UTF-8, it is encoded using 3 bytes because its codepoint is in the range of
0x0800
to0xffff
.
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 thex
are 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+28FD to binary:
00101000 11111101
. 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 10111101

Description
U+28FD, also known as Braille Pattern Dots-1345678, is a crucial character in the Unicode standard, specifically designed to facilitate communication for visually impaired individuals. This unique symbol represents one of the 240 possible combinations of six-dot patterns used in Braille, an essential system of tactile writing that enables reading and writing for those with vision loss. Each dot in the pattern can either be raised or flat, creating a total of two possibilities per position. The specific combination of these dots represents individual characters, which when combined, form words and sentences in various languages. Braille is utilized not only for written communication but also for accessibility in technology such as Braille displays on electronic devices. This versatile character plays a vital role in promoting inclusivity and equal access to information for people with visual impairments, while also contributing to the rich tapestry of cultural, linguistic, and technical diversity that defines our global society.
