Description

U+28DA is the Unicode code point for Braille Pattern Dots-24578, a character used in digital text representation of the Braille alphabet. As a key element of the Braille system, it enables visually impaired individuals to read and write using tactile feedback through touch. The character consists of six positions, each representing either a raised or flat dot, corresponding to binary values 1 or 0 respectively. In the context of digital text encoding, U+28DA ensures that Braille content is accurately rendered across different platforms and devices, supporting accessibility and inclusivity in communication. Its significance lies in its role as a critical tool for visually impaired people to engage with written language and information, reflecting the rich cultural history and ongoing evolution of Braille as a tactile writing system.

How to type the symbol on Windows

Hold Alt and type 10458 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+28DA. 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+28DA to binary: 00101000 11011010. 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 10011010
