Description

U+280B Braille Pattern Dots-124 is a character from the Unicode Standard that represents one of the 63 possible patterns used in braille. It serves as a fundamental component for creating digital text for visually impaired individuals using braille translation devices. The braille system, developed by Louis Braille in 1821, consists of various combinations of six raised dots arranged in a grid to represent letters, numbers, and symbols. U+280B Braille Pattern Dots-124 specifically represents the character 'b' in contracted braille, where the letter 'b' is translated into a single pattern consisting of two dots, with the first dot raised on both rows. This character plays an essential role in enabling communication and access to information for individuals who are visually impaired or blind, fostering inclusivity and independence within diverse cultural, linguistic, and technological contexts.

How to type the symbol on Windows

Hold Alt and type 10251 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+280B. 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+280B to binary: 00101000 00001011. 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 10001011
