Description

The Unicode character U+2899, known as BRAILLE PATTERN DOTS-1458, plays a crucial role in digital text by representing individual Braille cells for the visually impaired. This character is part of the Braille Patterns block (U+2800-U+28FF), which contains 237 characters used to encode the Braille script, an essential tool in many languages for converting text into tactile symbols that can be read by touch. The BRAILLE PATTERN DOTS-1458 character is composed of six positions, each with two states (raised or not raised), providing 64 possible combinations to represent letters, numbers, and punctuation marks. The Braille script has its roots in the French language but has been adapted for various languages worldwide, making U+2899 an important character in promoting accessibility and inclusivity in digital communication.

How to type the symbol on Windows

Hold Alt and type 10393 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+2899. 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+2899 to binary: 00101000 10011001. 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 10100010 10011001
