Description

The Unicode character U+2817, also known as BRAILLE PATTERN DOTS-1235, serves a crucial role in digital text by representing individual braille characters. As part of the Unified Braille System, this character encodes information for those who rely on braille for reading and writing. The braille system uses a series of raised dots to represent letters, numbers, and symbols, allowing visually impaired individuals to interpret written content through touch. BRAILLE PATTERN DOTS-1235 is specifically used to denote the presence or absence of dots in braille cells, with "1" representing a raised dot and "0" denoting no dot. This character contributes significantly to digital accessibility, making written content available for a wider audience.

How to type the symbol on Windows

Hold Alt and type 10263 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+2817. 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+2817 to binary: 00101000 00010111. 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 10010111
