U+2811 Braille Pattern Dots-15 is a crucial character in the Unicode standard that plays a vital role in digital text representation for visually impaired individuals. As part of the Braille system, it serves as an essential component for encoding alphabetic characters, numerals, and symbols in a tactile format readable by touch. The character consists of six positions, each representing either a raised or flat dot, creating a unique pattern that corresponds to a particular letter, number, or symbol. Braille Pattern Dots-15 is utilized in various digital platforms and assistive technologies such as Braille displays and embossers, facilitating accessibility for visually impaired users to read and interact with text content accurately. The character's significance lies not only in its practical application but also in its contribution to inclusivity, empowering individuals with visual impairments to engage more effectively with written information.

How to type the symbol on Windows

Hold Alt and type 10257 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+2811. 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+2811 to binary: 00101000 00010001. 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 10100000 10010001
