Description

U+2830 is the Unicode code point for Braille Pattern Dots-56, a character used in digital text representation of braille. This encoding system is crucial for visually impaired individuals as it allows them to read and interpret written information using touch rather than sight. Each braille character is represented by a specific arrangement of six dots, forming distinct patterns corresponding to letters, numbers, punctuation marks, or other symbols. Braille Pattern Dots-56 is unique in that it represents the letter "r" in English braille, with two dots raised above the other four. The use of U+2830 in digital text ensures compatibility across various devices and platforms, thus enhancing accessibility for users who rely on braille as their primary reading method.

How to type the symbol on Windows

Hold Alt and type 10288 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+2830. 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+2830 to binary: 00101000 00110000. 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:
