Description

The Unicode character U+280F, known as BRAILLE PATTERN DOTS-1234, plays a pivotal role in digital text by facilitating communication for individuals who are visually impaired. This character is part of the Braille alphabet, which was developed in the early 19th century by Louis Braille to provide an accessible writing system that could be read using touch. The BRAILLE PATTERN DOTS-1234 represents a specific arrangement of raised dots, where six positions correspond to different characters. Each dot can either be present (represented by "1") or absent (represented by "0"), resulting in 2^6 = 64 possible combinations. In the context of digital text, U+280F ensures that the Braille system remains consistent and accurate across various platforms and devices. This allows visually impaired individuals to access information using screen readers or braille displays, promoting inclusivity and equal opportunities in education, work, and social interactions.

How to type the symbol on Windows

Hold Alt and type 10255 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+280F. 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+280F to binary: 00101000 00001111. 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 10001111
