Description

The Unicode character U+281F, known as BRAILLE PATTERN DOTS-12345, plays a crucial role in digital text for the visually impaired community. It is part of the Braille alphabet, which consists of six dots arranged in a grid of two rows of three dots each. These dots are either raised or flat to create distinct patterns representing letters and numbers. U+281F represents one such pattern (dots-12345) that corresponds to the letter 'E' in standard English Braille. By utilizing these distinct dot configurations, visually impaired individuals can read digital text using a refreshable braille display connected to computers or other electronic devices, enabling equal access to information and communication. The BRAILLE PATTERN DOTS-12345 character is an essential component of this accessible technology, promoting inclusivity and fostering a more equitable digital environment for all users.

How to type the symbol on Windows

Hold Alt and type 10271 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+281F. 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+281F to binary: 00101000 00011111. 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 10011111
