Description

U+2819, also known as Braille Pattern Dots-145, is a crucial character within the Unicode standard that represents a specific arrangement of dots in the Braille system. Braille Pattern Dots-145 is used to form various letters and symbols in digital text. It plays an essential role in facilitating communication for individuals who are visually impaired, as Braille is a tactile writing system where raised dots can be felt with fingertips, allowing readers to interpret the meaning of characters or words. In the context of Braille, each character consists of a configuration of six dots arranged in a 2x3 grid. U+2819 represents the first dot in the top row being raised, while the second dot is also raised and the remaining four dots are lowered. This specific pattern is utilized to form unique Braille characters, contributing to the versatility and utility of this tactile writing system.

How to type the symbol on Windows

Hold Alt and type 10265 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+2819. 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+2819 to binary: 00101000 00011001. 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 10011001
