Description

U+28D9, also known as Braille Pattern Dots-14578, is a character primarily used in the encoding of digital text for visually impaired users. It represents one pattern among 6 possible dot configurations in the Unified English Braille system, commonly employed for translating written language into tactile format. This particular pattern consists of 3 raised dots arranged in a triangular formation, where the topmost dot is flat and the other two are raised. The arrangement of these dots can encode individual characters or words, depending on the context within the braille text. Braille Pattern Dots-14578 contributes to the accessibility of written information for individuals with visual impairments, playing a vital role in promoting inclusivity and literacy in diverse environments.

How to type the symbol on Windows

Hold Alt and type 10457 on the numpad. Or use Character Map.

  1. Step 1: Determine the UTF-8 encoding bit layout

    The character has the Unicode code point U+28D9. In UTF-8, it is encoded using 3 bytes because its codepoint is in the range of 0x0800 to 0xffff.

    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 the x are the payload bits.

    UTF-8 Encoding bit layout by codepoint range
    Codepoint RangeBytesBit patternPayload length
    U+0000 - U+007F10xxxxxxx7 bits
    U+0080 - U+07FF2110xxxxx 10xxxxxx11 bits
    U+0800 - U+FFFF31110xxxx 10xxxxxx 10xxxxxx16 bits
    U+10000 - U+10FFFF411110xxx 10xxxxxx 10xxxxxx 10xxxxxx21 bits
  2. Step 2: Obtain the payload bits:

    Convert the hexadecimal code point U+28D9 to binary: 00101000 11011001. Those are the payload bits.

  3. 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 10011001
