Description

U+284A (Braille Pattern Dots-247) is a character in the Unicode standard used to represent Braille, a tactile writing system for the visually impaired. This character, when utilized in digital text, denotes a specific pattern of raised dots that correspond to a letter, number, or symbol in Braille. In the context of Braille Pattern Dots-247, the arrangement consists of two raised dots on the first and second positions, and one dot on each of the remaining four positions. This pattern is commonly used for representing various letters in the alphabet, depending on its position within a word or sentence. The use of Braille Pattern Dots-247 in digital text allows visually impaired individuals to access written information through touch using Braille displays or other assistive technologies, thereby promoting inclusivity and enhancing communication across diverse populations.

How to type the symbol on Windows

Hold Alt and type 10314 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+284A. 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+284A to binary: 00101000 01001010. 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 10100001 10001010
