Description

U+2837 is the Unicode character code for Braille Pattern Dots-12356. This character represents one of the 6 possible dot configurations in the Braille script, which is a tactile writing system used by visually impaired individuals to read and write text. The Braille system consists of a series of raised dots arranged in a grid of 3x2 cells, with each cell either raised (representing a "1") or not raised (representing a "0"). In the case of U+2837, it specifically represents the dot pattern "12356", which corresponds to the letter "a" in English Braille. This character plays an essential role in digital text for accessibility purposes, as it enables visually impaired users to read electronic documents and communication using assistive technologies such as braille displays or refreshable braille embossers. The adoption of Braille characters like U+2837 in digital formats has significantly improved the inclusivity and accessibility of written content for individuals with visual impairments, facilitating their engagement with education, literature, and other forms of information exchange.

How to type the symbol on Windows

Hold Alt and type 10295 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+2837. 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+2837 to binary: 00101000 00110111. 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 10110111
