Description

The Unicode character U+1D2F, known as the Modifier Letter Capital Barred B, is a typographical symbol that serves a specific purpose in digital text. It is primarily used in conjunction with other characters to create diacritic marks or accentuations, such as a bar above a letter, indicating a particular phonetic or grammatical distinction. In some languages, these diacritics are crucial for accurate communication and meaning. While this character may not be widely utilized due to its relatively recent addition to the Unicode Standard (it was added in 2013 with version 7.0), it has the potential to become increasingly important as more languages and scripts are incorporated into digital text systems.

How to type the symbol on Windows

Hold Alt and type 7471 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+1D2F. 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+1D2F to binary: 00011101 00101111. 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:
    11100001 10110100 10101111
