Description

U+2858 is the Unicode code point for Braille Pattern Dots-457, a character used in digital text representation of the Braille script. Braille is a tactile writing system used by individuals with visual impairments to read and write through touch. In the Braille Pattern Dots-457, each dot position has a binary value assigned, where raised dots represent '1' and unraised dots represent '0'. This particular pattern is composed of three rows of two dots in a matrix, creating a total of six positions that can be either raised or unraised. These positions correspond to the binary representation of each character, allowing Braille text to be read by touch devices designed for visually impaired users. In terms of cultural and linguistic context, Braille scripts vary depending on the language, with different sets of characters used for different languages. This makes U+2858 an essential component in digital communication for millions of people worldwide who rely on Braille for their literacy needs.

How to type the symbol on Windows

Hold Alt and type 10328 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+2858. 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+2858 to binary: 00101000 01011000. 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:
