Description

U+28CF, also known as Braille Pattern Dots-123478, is a character within the Unicode standard designed to represent an individual cell in a Braille pattern. This specific Braille pattern represents the number 8 in the Braille numeral system, which is a tactile writing system used by people who are visually impaired or blind. The Braille numeral system consists of six-dot patterns representing each digit from 0 to 9. Each dot can be either raised (representing 1) or flat (representing 0), creating a total of 2^6, or 64, possible combinations for the ten digits. U+28CF plays an essential role in digital text by enabling visually impaired users to access numerical information through Braille-compatible devices, such as Braille displays and refreshable Braille embossers. By incorporating these characters into digital documents, web content, and software applications, developers can ensure greater inclusivity for users with visual impairments and contribute to the broader goal of creating accessible technology.

How to type the symbol on Windows

Hold Alt and type 10447 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+28CF. 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+28CF to binary: 00101000 11001111. 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 10001111
