Description

U+280A Braille Pattern Dots-24 is a crucial character in the Unicode standard, playing an essential role in representing Braille text in digital formats. As a widely used system for communication among individuals with visual impairments, Braille relies on tactile dot patterns to convey meaning. The Braille Pattern Dots-24 character specifically refers to the configuration of six dots arranged in a 3x2 grid, where each dot can be either raised or lowered based on the corresponding binary value in the source code. In digital text, U+280A facilitates accurate rendering and interpretation of Braille characters across various platforms and applications, ensuring that visually impaired users have access to information and communication tools. The Unicode character is a vital component of the ongoing efforts to promote inclusivity and accessibility in technology and written language.

How to type the symbol on Windows

Hold Alt and type 10250 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+280A. 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+280A to binary: 00101000 00001010. 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 10001010
