Description

U+2845 is a character in the Unicode standard that represents Braille Pattern Dots-137. This character plays a crucial role in digital text by enabling visually impaired individuals to read and interact with technology. In a Braille display, each character is represented by a pattern of raised or embossed dots, which correspond to the positions of the dots within U+2845. The character's cultural, linguistic, and technical context is deeply rooted in the accessibility domain, as it serves as an essential tool for visually impaired users to navigate various digital platforms and devices. By accurately representing these patterns in digital text, U+2845 contributes significantly to the inclusivity of technology for individuals with visual impairments.

How to type the symbol on Windows

Hold Alt and type 10309 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+2845. 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+2845 to binary: 00101000 01000101. 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 10000101
