Description

U+28C4 is a character from the Unicode standard that represents Braille Pattern Dots-378 (BRAILLE PATTERN DOTS-378). This specific Braille pattern is used in digital text for encoding and decoding Braille characters, which facilitate communication for individuals with visual impairments. The Braille system was invented by Louis Braille in the early 19th century and has since become an essential tool for the blind community worldwide. Each Braille character consists of a combination of six dots arranged in a 3x2 grid, where each dot can be either raised (representing "1") or not raised (representing "0"). U+28C4 specifically refers to a pattern where the first, second, and fourth dots are raised. In digital text formats such as e-books or documents compatible with screen readers, Braille Pattern Dots-378 enables visually impaired users to access information through touch, enhancing inclusivity and accessibility.

How to type the symbol on Windows

Hold Alt and type 10436 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+28C4. 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+28C4 to binary: 00101000 11000100. 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 10100011 10000100
