Description

The Unicode character U+1D30, also known as the Modifier Letter Capital D, holds a unique position in the world of typography and digital text. As a modifier letter, its primary role is to be used in combination with other characters to create specific diacritical marks or accents in various languages that use such accents. The character itself does not represent any standalone glyph or symbol but serves as a precursor for the actual accent being applied. One of the notable technical contexts where U+1D30 is used includes the creation of special characters in phonetic alphabets, like the International Phonetic Alphabet (IPA). In this application, Modifier Letter Capital D can be paired with other characters to create specific phoneme symbols that represent distinct sounds in various languages. In terms of cultural and linguistic contexts, U+1D30 allows for the accurate representation of certain unique character combinations found in less-known or minority languages. By using this modifier letter, typographers and designers can maintain the integrity of the original language's phonetic and orthographic systems when working with digital text. In summary, U+1D30, or Modifier Letter Capital D, is an essential character in the Unicode system that provides a foundation for creating specific diacritical marks and accents in various languages. Its role is crucial in maintaining linguistic integrity in digital text, particularly in phonetic alphabets like the IPA and in less-known minority languages.

How to type the symbol on Windows

Hold Alt and type 7472 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+1D30. 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+1D30 to binary: 00011101 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:
    11100001 10110100 10110000
