Description

U+28DB Braille Pattern Dots-124578 is a character in the Unicode standard that represents a specific arrangement of dots within the Braille writing system. In digital text, this character serves as a visual representation of the tactile Braille character used primarily by individuals with vision impairments for reading and writing. The arrangement of dots in U+28DB corresponds to the pattern "dot 1-2-4-5-7-8" in standard six-dot Braille configuration, where each dot's presence or absence indicates specific letters or symbols within the Braille alphabet. As a crucial component of digital text for accessibility purposes, U+28DB helps ensure that information is accessible to a wider range of users, including those who rely on Braille as their primary mode of reading and communication.

How to type the symbol on Windows

Hold Alt and type 10459 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+28DB. 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+28DB to binary: 00101000 11011011. 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 10011011
