Description

U+28D2 is the Unicode character code for "Braille Pattern Dots-2578," which represents a specific configuration of dots used in Braille script. This system, developed by Louis Braille in 1821, enables visually impaired individuals to read and write using tactile symbols that correspond to letters, numbers, and punctuation marks. The pattern consists of six raised or embossed dots arranged in a grid of two rows with three dots each. Each dot can be either raised (indicated by the character U+28D2) or not raised, creating 2^6 or 64 possible combinations representing different characters. In digital text, U+28D2 is typically used to indicate this specific configuration when Braille translations of written materials are needed for accessibility purposes. The character plays a crucial role in promoting inclusivity and equal access to information for visually impaired individuals across various cultural, linguistic, and technical contexts.

How to type the symbol on Windows

Hold Alt and type 10450 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+28D2. 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+28D2 to binary: 00101000 11010010. 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 10010010
