Description

The Unicode character U+2803, known as "Braille Pattern Dots-12," holds significant importance in the realm of digital text for visually impaired individuals. As a key component of the Braille system, it represents one of the six possible patterns in which raised dots are arranged on a rectangular grid to represent letters or numbers. Each pattern corresponds to specific combinations of these dots, enabling blind and low-vision users to read digital content using braille display devices. The U+2803 character serves as a foundation for the Braille alphabet, which consists of 63 characters (including digits and punctuation marks) based on the original 24-cell pattern. Inclusion of such characters in digital communication systems helps promote inclusivity and accessibility across various electronic platforms and applications, ensuring that individuals with visual impairments can participate effectively in today's information-driven society.

How to type the symbol on Windows

Hold Alt and type 10243 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+2803. 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+2803 to binary: 00101000 00000011. 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 10100000 10000011
