Description

The character U+28CD, known as BRAILLE PATTERNS DOTS-13478, holds a significant place in the realm of digital text and accessibility. This Unicode character represents one of the 63 unique Braille patterns used to encode letters, numbers, and punctuation marks within the Braille system. The Braille system, originally developed by Louis Braille in 1824, enables visually impaired individuals to read and write through a series of tactile dots arranged in six-dot configurations on a rectangular cell. In digital text, characters like U+28CD allow for the accurate translation of printed materials into a format that can be readily consumed by Braille display devices. The use of Braille Pattern Dots-13478 and other similar Unicode characters underscores the importance of digital inclusivity and accessibility, ensuring information is available to all users regardless of visual abilities.

How to type the symbol on Windows

Hold Alt and type 10445 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+28CD. 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+28CD to binary: 00101000 11001101. 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 10001101
