Description

U+2851 Braille Pattern Dots-157 is a character used in Unicode to represent a specific dot configuration in the Braille system. In digital text, it is typically employed to convey information for visually impaired individuals who use Braille as a means of communication. The Braille system utilizes a series of raised dots arranged in a grid pattern, with each unique arrangement representing a letter or symbol. U+2851 corresponds to the Braille Pattern Dots-157, which is distinct from other patterns and carries its own unique meaning within the context of the Braille alphabet. As an essential tool for the visually impaired, Braille has cultural, linguistic, and technical significance, allowing individuals with visual disabilities to read and write using a tactile system that transcends language barriers. Unicode's inclusion of characters like U+2851 reflects its commitment to digital accessibility, ensuring that Braille content is accurately represented across various platforms and devices.

How to type the symbol on Windows

Hold Alt and type 10321 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+2851. 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+2851 to binary: 00101000 01010001. 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 10010001
