U+28AD, also known as Braille Pattern Dots-13468, is a Unicode character primarily used in digital text for representing a specific cell of a 6x2 matrix used in the tactile writing system known as Braille. This unique character contributes to enabling visually impaired individuals to read and write using a series of raised dots arranged in various patterns corresponding to letters, numbers, and symbols. The cultural, linguistic, and technical significance of Braille Pattern Dots-13468 lies in its ability to facilitate communication and access to information for millions of people worldwide with vision impairments or total blindness. In digital text, U+28AD is employed to ensure the accurate conversion and representation of Braille documents across different platforms, software, and devices, thus enhancing the inclusivity and usability of electronic resources for all users, including those who rely on Braille.

How to type the symbol on Windows

Hold Alt and type 10413 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+28AD. 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+28AD to binary: 00101000 10101101. 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 10100010 10101101
