Description

U+284D, or Braille Pattern Dots-1347, is a critical character in digital text representation for the visually impaired community. This character is part of the Unicode standard, which aims to provide a unique code point for every character used across various languages and platforms globally. The Braille system was developed by Louis Braille in the early 19th century as an accessible form of written communication for individuals with visual impairments. Each character or symbol in the Braille alphabet is represented by a specific arrangement of six raised dots, known as cells. In the case of U+284D, it corresponds to the Braille code for the letter "L." The placement of the dots in this pattern helps users differentiate between letters and other symbols when reading tactilely with their fingertips. As digital technology advances, characters like U+284D become increasingly important, allowing visually impaired individuals greater access to information through screen readers and assistive technologies.

How to type the symbol on Windows

Hold Alt and type 10317 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+284D. 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+284D to binary: 00101000 01001101. 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 10001101
