Description

The Unicode character U+1DD8, known as COMBINING LATIN SMALL LETTER INSULAR D, is a typographic symbol that plays a significant role in digital text. It is used to represent the lowercase letter 'd' with an Insular style, which is a distinct script originating from medieval Ireland and Britain. The Insular script features unique shapes and forms that differentiate it from other Latin alphabets. This character is commonly employed in typography to maintain consistency within historical or cultural texts that use the Insular D, contributing to the preservation of such literary works. By incorporating U+1DD8 into digital text, writers and editors can accurately represent Insular script, thereby facilitating a more precise understanding and appreciation of historical linguistic styles and artifacts.

How to type the symbol on Windows

Hold Alt and type 7640 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+1DD8. 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+1DD8 to binary: 00011101 11011000. 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 10110111 10011000
