Description

U+28F4, also known as Braille Pattern Dots-35678, is a crucial character in the field of digital text for visually impaired individuals who rely on Braille as a means of communication. This character forms part of the widely used Braille system that represents letters, numbers, and symbols using a combination of raised dots arranged in a 3x2 grid pattern. The role of U+28F4 in digital text is to facilitate reading and comprehension for those with visual impairments by providing tactile feedback through touch-sensitive devices or software. In the Braille system, each character corresponds to a unique pattern of dots, with U+28F4 specifically representing the letter 'E' or 'G' in uppercase, depending on the context within a word. The use of Braille Pattern Dots-35678 in digital text has been instrumental in promoting inclusivity and accessibility for the visually impaired community, allowing them to engage with written content independently and effectively.

How to type the symbol on Windows

Hold Alt and type 10484 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+28F4. 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+28F4 to binary: 00101000 11110100. 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:
