Description

U+289C, or Braille Pattern Dots-3458, is a crucial character in the Unicode Standard, specifically designed for digital text representation in the Braille system. This system enables individuals with visual impairments to read and write through tactile communication. Each Braille character is represented by a unique arrangement of six dot positions, called Braille cells or patterns. U+289C represents one such pattern where three out of the six dots are raised, corresponding to the numeral '1' in Braille. In digital text, this character plays a vital role in converting text content into a format accessible by Braille readers, thus promoting inclusivity and accessibility. Its significance extends beyond visual impairment support, as it facilitates communication in various languages and scripts that have adopted the Braille system, including English, French, German, and many more.

How to type the symbol on Windows

Hold Alt and type 10396 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+289C. 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+289C to binary: 00101000 10011100. 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 10011100
